OK, I have a 74 duster with 318 and 727 tans. First time I had a problem it seemed like I was out of gas when the engine would not fire and the fuel filter appeared to be empty, the fuel guage read 1/4 tank and engine was cool. Filled tank, about 10 gallons, and it started and ran fine. This time fuel gauge was reading 1/2 tank and the car stalled and would not refire, again the fuel filter was empty and would not fill up after cranking engine. filled gas tank, took 7 gallons and it fired an ran fine. Has anyone else run ito this problem or heard of it before? I do not want to drop the tank if I don't have to or replace the fuel pump if thats not the problem.
