So I just put a new fuel tank, and fuel filter on my 65 mustang. Since I have had the car it has never had gas through the lines, im also willing to bet that it hasnt since the last owner had it being he didnt do much with it. So when I blow from the filler neck I get nowhere but when I attached a hose to the fuel line I can get fumes to blow out the fillerneck and the sound of air. Being the lines are empty is it to hard for the fuel pump to move just air? Is there anything I can do to make the fuel move? Also I dont have the gas tank anywhere near full could this be a problem?
