Re: Master Plan, Part Deux .... 2018/03/27 01:43:11 (permalink)
I wanted to do an extended run fuel tank set up.
I wanted to set it up something like this.

 
So the first thing I learned is that the Hondas and Yamahas seem to have a built in fuel pump.
So when the fuel from the factory tank is used, it begins to suck fuel from the remote tank.
 
It turns out that the less expensive generators do not have a fuel pump.
So every example I find online seems to point to setting it up like a gravity feed through a gas cap.
 

 
Ever watch one of those videos??
Every one of them only seems to show it running for a few seconds.
 
Certainly not long enough to empty the internal tank.
 
It leads you to believe that - as long as the line is primed - it will begin to draw the fuel from the remote tank.
 
I make wine kits, and have to do a lot of siphoning.
It is the same process, except with the remote fuel tank, it uses a primer bulb to get it started.
 

 
If you have ever done any siphoning of liquids, you know that once the process is started, it does not stop until either YOU stop it or the liquid from the top unit is finished draining.
 
So how the heck is this supposed to work with a remote fuel tank??
 
If my genny has only a 2.5 gallon or so tank, and the remote tank is 6.5 gallons....
And I begin to siphon from the remote tank into the genny tank....
The fuel does not magically stop just because the genny tank is full.
It will just keep going until the remote tank is empty.
 
I even did it with 2 pails of water as an experiment. Just to be sure.
And sure enough, the water just kept flowing out of the top pail until it was empty.
Glad I did not try this on the genny.
 
I also tried to rig up a pulse pump.
 

 
I tested this thing on the big genny, and it pumps quite a bit of fuel, but definitely needs to be primed.
 
But on this smaller genny, it did not matter if it was primed, it would not get more than a trickle.
It certainly would not draw fuel from a tank.
 
I think it's because there is not enough vacuum in these small engines.
But I'm not sure.
 
Back to the drawing board.

A remote tank sure would be helpful and convenient and pay for itself every single day,
 
I was surprised how much fuel the gensets factory tank took though on these 3500's. I think from dry I got 9 liters in mine, and it ran the 8 hours break in on that same tank running at the high rpm load setting most of the time. A fuel gauge would be helpful, since I dont know if I have 3/4ths a tank or sipping fumes, make s refueling become a pretty focused task 
 
Refueling at the begining of every day may just have to be part of the day, do you think the standard tanks runtime is to short for ONE days use in your case? now that im thinking about it, wherever we mount them, having them to be able to be refueled straight from a gas station pump into the generators tank would be nice and easy on the wrist.
 
Even if the truck itself doesnt need fuel every day, no real inconvenience to pull up to a gas pump. Save your wrist from that gas can weight.
 
I suppose a 10+ hour day at a festival or something along those lines you may need to refuel mid-shift

Here is my current brain fart...
 
I grabbed a couple of spare gas caps from Princess Auto.
Turns out the basic $8 cap for their 192 cc small engine is a perfect fit.


Used a hole saw to drill out the inner part.

 
Then CAREFULLY drilled out the outer ( black ) portion of the cap.
I say carefully because I destroyed the 1st one.
Don't know why, but these things are kinda brittle.
Next time I will use a spade bit.
 
So the next one started with a small pilot hole, then upped the bit sizes.
Ended with using the step bit.
 
I made sure that the hole was a teeny weeny bit too small to get my threaded hose barb in there.
So I used my torch to heat up the barb a bit.
While hot, I threaded it into the cap.
Nice tight fit.

 
So I have this.
 
Now the current plan is to tap into the truck's gas line, and run a new gas line to the back to the gennys.
I will use an electric fuel pump (on a switch) to bring fuel to the gennys.
Try to set it up so that there is one single line.
Branch off to each genny. Each will have its own shut off valve.
 
So I should be able to flip the switch, and pull fuel from the big truck tank, via the electric fuel pump.
Just open the valve for whichever genny needs fuel.
I should not have to carry an extra gas can.
Should not have to fight with the gas station pump and the genny every day.
 
Not perfect.
But not bad either.
 
Now to try to rig up SOME kind of gauge so I know when its full.
 
Wondering if something like this will work???

 
It doesn't give me levels, but might be enough to tell me to shut off the pump.

The electric fuel pump straight from your trucks big tank is a great idea. I think mine being a 2000 with all its evap sensors would probably throw 8 codes If I messed with the system.

If the big tank already has a tank drain plug on the bottom would make for a good easy explosion free place to tap in

Have not looked for a drain.
Hoping there is just a rubber line.
 
It should work for you too if you can tap into a line.
It will only get used when the truck is parked.
It will have shut offs everywhere.
Should not affect anything else.
 
Got all off ebay.

Well, we had a few nice days, then it went bitter cold here.
Almost -30 the other night.
And I need to work on the OUTSIDE stuff.
Like GRAPHICS !!  Can't do anything in this cold!!
 
So keeping busy in the garage.
A couple months ago me and a buddy drove 10 ish hours through a blinding snowstorm to pick up a hat dog cart for him.
He tore it down, and refurbed it. Got it all back together.  Now I get to do my thing...  WELDING !

Around here the rules have changed a bit. Anything covering the cart ( umbrella ) must now be certified non combustible.
What the hot dog guys are doing is buying a good quality umbrella ($200) and then taking it to the tent and awning places and getting them to recover it with fire retardant material ($600). Yeah, $800 umbrella!!
Instead,he bought $300 of steel, and borrowed a roll of aluminum sheeting form his cousin, and let me go to town on it.
Pretty much done all the framework.

 
 
Can't get more non combustible than steel.
Even designed in a ridge vent along the entire peak.
Making it so it lifts up about 15 inches with a hydraulic jack.
 
Added front and back fold down shelves for the coolers.

Lotsa fun.

That outa the way, I finally got the right parts ( trial and error ) to piece together my exhaust system for the generators.
Tested it out today, and they worked better than expected.

 

 
The 2 larger silver things right in the middle are fire hose parts/ couplers.
I am using them as a quick disconnect.
I need to do regular oil changes on these gennys.
I am going to have to take them off to do this.
I don't want to have to try to unthread these pipes every time.
Besides the pipes lose their threads when you take them off and on a few too many times.
Luckily, the fire hose parts are standard 1 inch pipe thread.

So it hit me at 3 am, I can't connect the 2 pipes like I did in the pics.
I'm pretty sure it will cause problems. So I will run them separate.
 
Tested a few things.
A larger diameter pipe does not work. It changes the acoustics, and makes a lower tone kinda rumble, which I find louder.
The couplers work great. And dissipate the heat better than the rest of the pipe.
It ran consistently about 85f.
And the end of the pipe ran so cool that I could hold it for a long time....  just warm.

Holy crapoli it's been chilly out.
Finally got to test the two genny's in parallel.
 
Seemed to work just fine.
Put a load on it, watched the gauge, the wattage balanced between the two units.
 
I took some advice I saw somewhere, and ordered the Champion parallel kit.
Because it has a 50 amp breaker, and it works with the expensive cord I already have.
Also, I am thinking of try to link 3 units together.
Others have done it, with other gennys.
 

 
The one they are currently selling at Harbour Freight is NOT the right unit.
It is meant for the smaller generators.

The one problem is that the Champion unit has SQUARE plug ends.
It comes with ONE set of adapters to plug into round holes.
Yeah, seriously, square pegs into round holes.
Story of my life....
 
So you have to get a little creative if you need more adapters, because I can't find any on ebay.
 
The other problem is that the connectors do not lock in the holes.
One already vibrated out.
Gonna have to address that with some caulking or something once they are installed on the truck.

I want to re fuel my generator directly off my truck's fuel tank by tapping into the line, and using a 12 volt fuel pump.

Trying to figure out a simple way to prevent overflow / spillage or even touching the gas or cap, since it might be done while working.

This is what I came up with.

Small plastic tube, holes drilled in the bottom to allow fuel in/out. Inside is a non absorbent piece of foam.

Through the gas cap.

Also a hose barb through the cap connected to a fuel line with the pump pulling fuel from the truck's tank.

Fuel goes in, as it gets close to the top.... the foam floats to the top of the tube. Turn off switch.

Thoughts??

 
I will make sure the top is vented.
If it works, I will try to find a stainless steel tube.

I know, seems like everyone is getting crap weather lately.
Well..... not HPX..... because HE is is Florida..... where it is BEAUTIFUL all the time....
 
Anyway, still going down to -20 at night around here, so it's been too cold to re- install the water system, or do much outside.  Need to do these little things so I can get my HD inspection.
 
So instead, I'm helping my buddy with his hot dog cart.
 
Did a full tear down and refresh.
Welded together a full metal canopy.
 
And finally got to play with my vinyl cutter.
Figured I need to practice a bit before I tackle the truck.
This is fun.

Got my gas level bobber figured out a little better.
I was worried about what prolonged exposure to the fuel might do to the plastic tube.
 
Got this stainless tube that was the same size.
Its cheap stainless steel, but should work well.
Drilled a hole in the bottom and drove a stainless screw through it as a stopper, so my float would not fall out.

 
 
Took the plastic tube and mounted it on the top so I could see the bobber when it surfaced.
 

 
I didn't like the tape I started with, so I switched to heat shrink.
 
Mounted it all in the cap.
Sealed with clear RTV.
Also drilled a small vent hole in the cap for gas expansion.

Does that year model have a fuel pump inside the gas tank?  If so, it will pressurize your generator fuel line when the truck engine is running.  If you forget to shut the shutoff valve when you crank the truck you could start spilling fuel out the back.

Now that I passed all my inspections, I've been busting my butt trying to get my generator array all set up.
Had to reconfigure all the parts of the framework and box I made. 2 or 3 times.
Forgot to take pics during the building of the box.
Just have shots of it now done.
It looks ok from the outside. But I know I could make it structurally better.
Guess we will just see how we make out this year.
Hate being rushed to get things done, but I gotta get working.
Still have graphics to do.
 
This is the finished box.
I made use of some hood baffles that don't fit my hood.
But they make good doors, and are fully vented.

Goofy idea, but it worked well.
 

 
Used some insulation to try to deaden sound as much as I could.
 

 
I made exhaust pipes out of black steel gas pipe.
Pointed it down below the truck.
Had to cut out this back panel to make it work.
Started by just cutting these sections out, but ended up just cutting it all away.

 
It was just hollow behind the panel anyway.
It gave me an extra couple inches of space.
 
Then I pointed all the exhaust pipes out the drivers side.
Not really the way I planned it, but it will have to do for now.
The 24 inch fan I have in there helps to pull air through the box and should blow any exhaust away.
 

 
I really thought I would port all of the pipes into 1 pipe and then send it up towards the roof will a tall stack.
But during the test runs, there is a LOT of moisture coming out of the exhaust. 
So unless I figure out what to do about that, this is the way I will use it.
Still way better than the guy that mounts his Honda genny with the exhaust pointed TOWARDS the serving side!
 
Took to a fairly busy street and did a test burn.
With the traffic noise, you practically can't hear the generators at all.
And I am trying to hear them.
Overall, pretty happy with that.

So what do you do when you spent 2 days and you finally get the generators mounted and the exhaust figured out...
That's right
Rip it all off and start again!
 
The generators are pretty quiet.
You can barely hear them from the out side.
But inside.....  not so much hear them, but FEEL them.
The vibration was pretty substantial.
I asked around, and was told either lean to live with is or spend 12 grand on an Onan.
 
But I figured it out.
The vibration can only be transmitted through the only 4 contact points to the platform, the wheels.
The are made out of a hard hollow plastic, attached to steel pegs.
 
So I got these Anti vibe isolators.
Did enough research to understand that they are not JUST plain old rubber.
Special compound.  Dense yet very elastomeric.
 
Anyway, I found these feet / mounts.

 

 
Ripped out the stud, and drilled a hole in the center.
 

 
Used a piece of hose for a spacer.

 
And mounted the new anti vibe wheels.
 

 
A little smaller than the originals, but still worked well.
 

 
They absorb almost all of the vibration.
Hardly feel a thing now.

Seeing as the gennys are coming out anyway for the wheel retro fit...
I'm not really happy with the exhaust pipes.
They work, but they are ugly, and kind of a mess.
 
Noticed today, how motorcycles have all the pipes come into a collector, like a header.
Did some research on that stuff.
Found these among others.

 
But not wanting to pay several hundred dollars for a piece like this, I tried to figure it out for myself.
 
I got a 3 inch to 2 1/4 adapter, and had some steel pipe left over.

 
It was pretty heavy pipe, so I had to grind down the ends enough to stuff into the pipe.

 
As I tapped them in with a hammer, the adapter started to change shape to accommodate the pipes.
It turned into a square shape.

 
Once in, I started to weld the pipes together.

 
Tomorrow I will finish up all the welding.
I will fill all the gaps with weld.
Then add some extensions and threaded ends to attach to.
 

 
This end will get attached to the pipes coming off the generators.
 
I think I will run the other end into one of the truck mufflers I have.
Then I will only have ONE exhaust pipe sticking out.
 
MAYBE, I can get it to run up out the top.  That would be so sweet.

Got it welded together.
Filled all spaces with weld.
Could have cleaned it up better, but its going to be hidden.

Sprayed with galvanizing paint.
Looks like the beginning of a new star trek ship.

LOTS of work, and test, and fit, and adjust, and repeat....  about a dozen times....
MUCH happier with how the exhaust system is now.

 
I had no clue what I was doing... only a vision of what I wanted.

Once I got 3 of the 4 figured out....


 
The 4th one just fit into place.


Kinda hard to see it.
This shot is from below the generator platform.
All the pipes come down and go into the collector on the left.

I hope I don't have any issues.  It is no lower than the diff.  But not going off roading any time soon.
 
Today I got the collector attached to a small car muffler.
Was even able to tuck it up and outa sight.
Even made my own exhaust hangers out of some old conveyor belt I had.
Cause up here, fricken hangers are $12 a piece.

uuuhhh.... I mean, ....  I wanted to do my part for the environment and upcycle as much as possible.
Reduce, re use, save the whales.... all that.

Got some more shots from below.


 
All the pipes go into the collector, and then to a flex pipe, then to a small muffler.
 

 
That somehow I managed to get tucked up nice and hidden under the body.
 
Still have the exhaust exiting out near the fan to blow it away.
But at least its only one pipe.
I still have the option to turn it upwards.
Will have to see if that happens.

And of course, just when you figure you are a fricken genius for making this all work....
I go and make a dumbass move and while drilling a hole for a bolt, I manage to hit a wire.
That wire was connected to the reverse lights.
Which is also connected to the backup alarm.
And the back up camera.
 
yup...
 
The entire interior is buttoned up and sealed tight.
Only one way in.

 

 
You can see the wire wrapped around the thing I drove in the side.
What a ma roon !!
 
All good now.
Hopefully the decals will cover it.

With the exhaust done.  It was time to get the generators going together.
I had the Champion parallel kit, but sent it back.
I hated the square to round plug converters.
For one thing, the stuck out too much.
Plus they we not a good fit.
They vibrated loose in testing.
 
I ended up getting the kit from Northern Tool.

 
Their generator is basically the same as the Predator, just more expensive.
So the parallel kit was made for it.
The plugs have a retractable spring loaded sleeve over the prongs, so you don't accidentally get electrocuted.
They fit GREAT.  Nice and snug.  And they are bent at the end, so they don't stick strait out.
 
The one problem is that the receptacle does not match my (very expensive) cord.
And it is a 3 wire. My cord is 4 wire.
The Champion was a match.
 
So I grabbed a matching socket from Menards when I was there last.

I had to go from this:

 
To this:

 
So I popped it open and took a shot of the wires.

 
At first I had the red and the black opposite each other, like the original unit is set up.
But I was only getting power on one side of the panel.
And after a few failed attempts, and some research, I figured out that this configuration works.
 

 
This is only putting out 120, not 240.   (I knew that going in)
So I had to jump the black wire across to feed both sides.
 
I am pretty sure that is how the Champion unit was wired as well, but I only took one pic, and it's not very clear.
I HOPE I did this correctly.
I can't find my tester, so I'm going to have to go grab one tomorrow.
 
But everything works.
Full power to the entire panel.
The same way it did when I tested to Champion unit.
Nothing blew up.
 
I tested it for a couple hours with a good load.
 
I bought 2 of the parallel kits.
Stripped down the 2nd one.
And made it so I can hook 3 generators together.
I tested it for a while with good results.
It evenly spreads out the loads across all 3.
 
Just not sure if I want to trust it.
I want to test it a little more before I decide.

Well lets hope failure truly is the mother of success.
Because the generator exhaust was kind of a failure.
Not totally, but enough to make it feel like a big set back.
It turns out that generators vibrate -  alot.  duh... whoda thunk?
When tied to solid black pipe ( or any pipe ) that really have no give.... things start to vibrate loose.
Because of this, I had a lot of exhaust leakage right where the exhaust started - at the generator.
 
Most of the black pipe and the muffler worked out just fine.
Just need to re - figure part from the generator TO the pipe.
 
Scrapped the neat flange thing I made.
Figured I need a proper tight fit around that little stubby pip that sticks out.
Came up with this brass pipe that is smooth on one end, and a nice 1/2 inch pipe thread on the other.

 
Problem was that it was the exact same diameter as the little stubby pipe.
So I needed to expand it a bit.
I did try a larger pipe, but I could not get it to stay on tight.
 
I have a mish mash of socket sets around here.
11/16 from 4 different sets all have different outside diameters.
So one at a time, I tapped the sockets and extensions into the brass pipe until it was expanded enough to slip over the stubby pipe on the generator.
Crude, but it worked.

 
The next problem was that there are no muffler clamps ( at least locally ) that would fit around this.
I found that a clevis pin works great. Maybe even better than a muffler clamp because it has nice even pressure all around it.

 
I had to grind out the inside just a bit.
I also replaced the pin with a bolt and a nut to lock it down.
 

 
So far so good, should not be any exhaust leakage.
 
From here, I am using flexible stainless gas line.
This should take care of the vibration problem.
The pipe will have some give.

 
Not sure how it will work in the end.
Research showed that it has a heat tolerance to 500 f.
 
I ran the genny for an hour with this pipe on it,  and the external temp was around 250.
 
Still not sure if I am going to try to use the cam lock couplers again or not.
They are great, but they keep popping open from the vibration.
If I use them, I am going to have to try some metal straps to keep them locked.
Kinda not so quick release then.

Well for a day that was forecast to be thunderstorms all day... got a whole lota nuthin.
Which was good, because I got a lot done on the truck.
Got the entire exhaust system better secured.
Got 3 of the generators installed.
Added an extra vent to the top of the box to let out the rising heat.
It's ugly, but it works.

 
Added that rear vent for my air conditioner exhaust.
Who knows if it will help any??
But it's worth a shot.
 
Even added a hitch receiver while the generators were out.
I have a small ( light ) trailer.
Never know when I might need to haul some extra supplies.

 
So assuming the flex pipe holds up to the heat...then it appears to be a success!
No more rattling.
No more pipes shaking.
Way quieter overall.
Decided to not use the quick release things. 
The flex pipes were only a foot long, but I got it set up so that they are easy to reach and should be easy to undo.


I went and shot some video on a street with decent traffic so try to simulate what it would sound like with the generators running while doing something like a lunch service downtown.
 
I almost can't hear the generators running when standing at the service window.
 
I had all 3 generators running at the same time.
 
Here is the link to the video.
 
Because the insert video button does not seem to work.

I am truly beginning to feel as though this will never end!
 
Had to make one more adjustment, so all the generators came off AGAIN!
 
There are a couple of other things that I wanted to do but I was going leave until later, but now they are off again, so lets just get them done now.
 
At first I thought that I was going to make them easy to take off and put back on so I can do oil changes.
But the reality is that every time I do it, it's really a long ( like a couple hours ) process.
 
So I figured I could set them up to do oil changes while still mounted to the truck.
 
Drain the oil, clean it up.
On the Predator 3500, the oil drain and fill ports are close together.

 
Took a bit of searching, but I ended up at a local machine shop that deals in fittings.
The oil drain plug is an M 10 x 1.25 thread.
They had a fitting for it and a brass fitting to match up.

 

 
Add a hose and a shut off valve, and we have a simple drain system.
 
The filler port was a real PITA.
They did not have anything that matched the thread on the fill plug.
I cut off the unnecessary parts, and carefully drilled it out.

 
Used a 1/4 inch threaded pipe, and threaded it into the plug.

 
Installed both into the generator.

 
The drain hose went out the bottom where the oil drain opening is, and the fill hose goes out the side where I have already removed the little door and replaced it with air filter.
 

 
Viewed from the back you can see the drain hose coming out the bottom.

 
BTW, the flex hose for the exhaust was the best thing I ever did.
It works fantastic.

Looking good. You might check some of the marine shops for the drain hose and valve. A lot of people install those to drain oil on their inboard boat engines.**Never mind...just saw the pic with the hose and valve.** :) Another option would be getting an oil change pump and sucking the oil out from the filler port. Keep you from having to use a pan.
