    Walbro 255 GSS341 intank fuel Pump problem

    I just finished installing and putting my car back together and the fuel pump sounds like it's priming, but I don't have any fuel pressure??? I followed the directions to the Tee. And YES I put gas back into the tank. Any help would be greatly appreciated.
    Thanks, have a great Sunday Evening and God Bless Our Troops and the U.S.,

    I use AutoMeter fuel pressure from the end of the fuel rail. (Electrical)
    I even removed the Nitrous Fuel line and no fuel.
    Any Help Would Be Greatly Appreciated,

    Maybe a kinked fuel line... It happened top me when I did mine... I installed an aluminum line the second time around. Those plastic lines suck.

    I'd say you have a kinked line or one that's fell completely off or something along those lines.

    It might have come off. I used the straw/ accordian white plastic hose. The one that looks like the factory one. and used hose clamps, This Sucks!!!!
    Thanks for the info,
