Onan generator 5500
I have a 2016 keystone raptor toy hauler and my 5500 onan generator runs for about 30 min and shuts off. It will start again and run fine but if you turn on anything more than lights or TV it shuts of...

Another thing to look for is degradation of the rubber fuel lines. with the crappy ethanol in the fuel it eats at the rubber. My fuel station line between the tank and pump was toast due to this. I replaced the entire fuel line from tank to pump with 3/8 copper, short rubber hose on each end that is rated for the new fuel.
JFYI,,,
With all due respect, my opinion...
Copper is not the best choice for fuel lines on vehicles, at all.
An unbalanced tire at hyw speeds can set up substantial vibration that kills copper tube fast. If its mounted tight, every 6-8", might still be ok. But then chafing comes into play. And copper is very susceptible to chafing thru with continious vibration with a hard surface.
Copper (especially 3/8" copper tube) work hardens under vibration. Then is prone to cracking and fuel leaks. Coppers very good heat transfer properties make for a easier tendency to vapor lock.
If you don't want to use a quality fuel rated hose, then use copper clad steel fuel lines, or the new Ni-Cop tubing.
