Thread: Not getting gas??

FIrst of all, I would want to be sure that pump is really working. Pull off the intake line at the pump, have someone crank it while you put your finger over the hole and see if it is sucking. You will feel some suction on your finger if it is. If it is, then you need to backtrack. Remove the gas cap and put some compressed air into the line that goes from the pump to the tank (not a lot of pressure, maybe 30 lbs) and have someone listen to see if they hear gurgling back there. Air should flow pretty easily through that line. ( I don't think that model car has an inline filter BEFORE the pump).

I had a similar problem on one car one time and when I put the air to the line it momentarily wouldn't flow, then all of a sudden I heard something blow off of the line and air went through. Turned out that sock on the end of the line was blocked and once it blew off it allowed air to pass through. I just left that sock floating around in the tank and it never caused any problems.

There is no magic to this system.......you have a tank (that needs some sort of vent so as gas is displaced air will be able to enter), a fuel line, and a pump. If everything is clear and the pump works, gas has to flow.

I just had another thought. You said you put the fuel pump from a 350 on the 400. Maybe the two are just different enough that it won't work. Could be a difference in the configuration of the arm or whatever, but check that out. Sbc should be sbc, but sometimes they make slight differences in parts from model to model............your finger test should tell you that though.
