Ok so I'm trying to fire up this 71 Olds today that I've been working on. Fresh motor with all new accessories, etc. It's a 455. Well for some reason the fuel pump isn't pulling fuel from the tank.

If I remove the inlet hose and stick it in a cup of fuel it pumps it no problem. If I suck on the line coming out of the tank I get a mouthfull of gas (threw that right back up). So the pump pumps and the line flows....yet when I put the two together I get nothing. Anyone have any idea? Pump not strong enough to pull fuel all the way from the tank??
