Gas not getting to generator

Welcome to the forum!


We're sorry that it has taken a problem for you to join us, but we hope that you will stay engaged after you have a resolution.

Unfortunately, they are right. Your pump works, your generator works...but your pump cannot lift fuel from the tank. Sure you can blow bubbles into the tank, but the fuel pump can't overcome much of an air leak on the suction side.

This is the dreaded fuel tank issue. How to get to the top of it (maybe through a hole in your floor)? I ran an assumed MPG against odometer for years on my 1997 Bounder as dropping the tank to fix the fuel gauge was quite a project. I lived crossing my fingers to avoid the deadly F53 fuel pump issue to avoid dropping it.

Maybe you can reach in and get to the generator line...maybe the tank needs to be dropped. Hate the idea of an auxiliary fuel tank for the generator, but I just might do that too!

I did the aux. bit temporarily since it probably wasn't up to standard in many books. Sold the coach 9yrs later and left it to the second owner for further evaluation.
My permanent fix, was to remove the fresh water tank, out from under the bed and for making an access hole, but somehow never got around to it.

When I replaced the fuel pump in my F53 a couple months ago, I replaced the fuel lines to the genny and also the EVAP return lines. They were both dry and brittle..

If you're considering going inside the tank, take a look at the writeup with photos.. If you go in there, I'd replace the fuel pump and all the hoses while you have the tank dropped..

When you replace the fuel line use fuel injection fuel line it is heavier duty.
