Onan 5500 Stops Running after 15 minutes
I have a Class A gasser with the 5500 Onan generator. It has only 70 hours on it and it has run just fine until recently. I start the generator from the inside control panel and it has no proble...

I took the motorhome to a Onan dealer and he suspected the fuel pump and recommend I replace it. He wanted $172 for it and a filter just for the parts.
I went ahead and found out that Airtex makes the fuel pumps for Onan and I ordered one on Amazon. Airtex E11015 Electric Fuel Pump for Onan Generator Set for $44
Here was one of the comments on Amazon:
This was an exact replacement for the original Onan/Cummins 149-2620 fuel pump. My original fuel pump developed the fairly common problem of causing the generator to stall after about 20 to 30 minutes then requiring a cool down before it would restart and run for another 20 to 30 minutes. I only have about 15 hours on the generator since replacing the pump, but so far, so good.
