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.

Cool updates always like seeing those engenious ideas your thinking up.
 
Really like the fold away cooler stand for the cart aswell
