Replace all rubber hoses in that area (engine supply, engine vapor return, generator supply). Will save you lots of hassle in the future.

I got the new pump assembled and installed in the tank, connected the hoses and electrical harness, raised the tank and attached the straps with a few turns of the bolts just to hold it in place. Iíve done these sorts of things enough times to know not to install something all the way until you make sure it works. Anyway, I put in 8 gallons of gas, connected a pressure gauge to the hose that goes to the mechanical pump and then powered it up. Held at a steady 4 psi. Guess thatís normal, Iíll have to check the manual. Went to check for leaks at the tank and fuel was coming out of the pressure regulator, the thing in my first picture. Guess Iíll have to drop the tank back down. No way to get to it otherwise.

fuel pump problems

I had the same exact problem with my P30 chassis 454. Dropped the tank and found that hose connecting the pump to the engine supply line has turned to mush...I suspect that the ethanol that is put in our fuel is to blame as well as father time. The replacement hose supplied with my new pump is neoprene and should resist ethanol fuel. Glad you found the problem which I was going though about the same time.
