Onan Genset Fuel Issue

[ArmyGuy51]

Running generator on the highway; coach fuel level dropped to 1/4 tank and generator shut off which is normal. Fueled up coach and attempted to start generator; generator starts up and runs for 7-10 seconds and shuts down. Let it set and it will do the same. Is there a way to prime the fuel supply or am I missing something else? Thanks

My Onan primes by holding down the stop button. If you do it at the GenSet it is easy to hear the pressure build up.

I have an Onan troubleshooting guide I can send you via e-mail (.pdf format) if you need it. I think it is online as well if you google it.
