a long time ago, when I was 16 I had a '32 plym@outh and i used to put pressure in the fuel tank to sent fuel through the system. I took a piece of inner tube with the valve and clamped it on the fuel filler neck with a radiator clamp. then I pummped air into the tank with a bicycle pump. the pressure sent the fuel through the fuel pump and into the carb. newer cars have vented tanks but not old trucks!
