Default Onan 2800 fuel pump

Hi
I have a 1997 RT. Dodge 3500.
I have the factory Onan 2800 generator.
I think the fuel pump is not working?
New fuel filter, runs with starter fluid applied.
No fuel comes from fuel line ?
Any idea where to get a replacement?
And what the part number is?
Thank you
Eddie

I have the same problem. Waiting to get it checked by an authorized local generator repairman. (I suspect is air in the line because the fuel line went bad and was leaking gas. But, I also have the owner's manual so I can give you the part number. I'm just not sure what part you need. Is it the fuel pump? Also, if you have a cell phone, I can text you pictures of the pages from the owner's manual.

Different RT and may be different Onan (mine is a 2800 though), but I went thru this and documented my resolution. Exact part numbers can be found on the web or by calling Cummins.

Before you drop the generator and buy a new fuel pump, disconnect the fuel line from the tank and connect a temporary line from a gas can and try start the generator. My 1999 RT 2800 Microlite would not start, no fuel coming out of line when disconnected from the carburetor. I was going to replace the fuel pump, but when I tried it using a 2 gallon gas can it ran for more than an hour with the A/C running. I'm now going to replace the original fuel line from the tank. The original fuel line is hard as a rock.
