I replaced the fuel pump and filter on my Onan 5500 generator after I started getting error codes that the genset wasn't getting fuel. It ran fine for about two hours. Now I'm getting the same error codes. I took the fuel line off the carb and it seems like the fuel pump is sucking air. The fuel tank is over half full. To me this sounds like either a crack in the fuel line or the dip tube has fallen off inside the fuel tank. I don't want to drop the underbelly liner if I don't have to. This is on a 2008 cyclone 3795. Has anyone had this problem?
