how many mile son the chassis? when you say not getting any fuel out of it do you have an actual fuel pressure gauge on the rail or your trying to free flow it to test it. more info please. could be a clogged fuel filter

Well it should be louder than oem so if that was worrying you, you can relax about that. Definitely check the fuel pressure.

Ok yea I know that it's gonna be louder I was jus stating that so no one would ask and I've put a new fuel filter,.. Also Ive tried to jus prime it by cranking and nothin, soo I took Off the Bango hose off the fuel pump and noo gas came out what so ever. And when I first took off my oem one gas kinda sprayed out and that's what worries me that after cranking the car there's no pressure in the lines (with walbro)...

if the pump is definatly turning on then you have a blockage in the line. if the pump isnt turning on then could have a bad ground or main relay

Uhh that sounds like you need more juice, have you checked your battery voltage? Try jumping your car.

I would remove the pump/s and hook them up to a battery to be sure they are working. It wont hurt them I have been using an old 255 for several years unfused as a diesel transfer pump and its still going.

Is it possible the line from the pump to the hangar bottom is loose or split?
