I just converted over my used 40lb fryer from NG to LP. I changed all the orifices, pilot light and the rubber piece and spring inside the regulator. They sent me a new regulator, but it wouldn't fit. But the instructions said to just change out the rubber piece and the spring inside the regulator. I have a 100# propane tank. The only hose I have right now is one from home depot for home appliances. I started it up and it ran for a few minutes and then shut off. Now it won't stay lit for more than 20 seconds. I hear the gas flowing in the pipes until it turns off. The pilot lite will stay lit, but when I turn it to on, it shuts off with a "pop" sound and the gas stops flowing from the tank. I'm hoping all I have to do is change the hose to a bigger one, but I'm not sure. Everything is pretty clean. Any ideas??? Thank you for the help.
