Here is my challenge. When my tank is full the car is undriveable. It acts as if it is starving for fuel. If I drain the tank down to about half it runs perfect. This has been going on since I took it out for the summer last year. I have replaced so far: fuel pump, pulsator, sock, inline filter and relay. I even tried to simulate the problem by placing 120 pounds of weight in the back of the car while having a half tank to simulate the extra weight of ten gallons of gas thinking that maybe something is getting pinched by the weight of a full tank. No go. I have tried the full tank several times and each time it was undriveable, it wont idle and to keep it running at all I have to pump the pedal continuosly. I drain it to a half and it's fine. The tank looked ok inside from what I could see when I replaced the pump. I am questioning a venting problem but do not know how or if thats possible.
Thanks in advance,
