Onan 5500 Generator

When it's hot oustide my genny runs for about 30 mins and stops. Code 36. Fuel pump looks fairly new although the RV is 10 years old.

Took a picture of the underside hole under the genny. The shiny thing is the fuel pump.

Looks to me like the exhaust pipe would be heating the heck out of both the fuel pump, the oil filter and the genny in general. Should there be some sort of shroud over this hole?

  • It's difficult to answer without being there to feel how hot the pump and filter are getting. Perhaps run the Gen until it quits and feel how hot the pump and filter have become. Then cover the hole with a cheap aluminum soffit vent from a big box store for a few bucks and see if it made a difference.
