I have been working on a 54 Chev P/U for a friend. Recently it wouldn't start for him, and I traced it to a fuel pump. It definitely wasn't pumping any fuel, and had a bunch crap in it and both fuel filters. Anyway, I took the pump apart and cleaned out the crap, and the pump are now pumps and sucks in from the inlet. The problem I am having is the fuel outlet appears blocked? I cant blow our suck through the outlet side... at all? I probably should just get a new one, but I wanted to ask here first.
