so i had originally hooked up these clear lines to the lift pump mounted to the truck and it wasn't sucking fuel from the supply line. thats when i grabbed this test pump and tried. i have a follow up video to this one, i think the pump was fine it was the check valve on the pump that was actually stuck closed, i just didnt know at the time of this video.
How did you know the lift pump was bad
