Hi Have a new Tank,( mounted below the bed) & new line to Stock reconditioned Fuel pump, Truck has been running but now I find that fuel is not been devivered to the carb. I disconnected the fuel pipe from the carb & attached a clear tube to it. I then sucked thru fuel until it was visible in the tube.
When I stopped suction on the tube the gas ran back down the hose
Is the suposed to be a non return system in the pump?
