    My fuel tanks have 3 lines running to them. They have a fuel supply line, fuel return line, and a vent line. Will it mess anything up if i block off the fuel return line?? /forums/images/graemlins/truck.gif

    yes! If it's fuel injected a lot of fuel is sent back to the tank, if it's carburated not as much goes back but the mechanical pump still returns a sertain amount.
