How is this tank vented i know it has 3 vent ports in the tank that go to the contraption in the car what is it? then 1 line comes out and goes to the motor evap line thanks
Short version, the item is a vapor separator to collect fuel vapor off the three lines from three locations on the top of the fuel tank. Then vents into the intake by the charcoal canister system. This works with the non vented gas caps.
