Hayden I looked a my truck with a flashlight outside and I also replaced the
rubber tapered hose.I think mine is hooked up with the big one toward the
rear of the truck going to the pump.I have a vacuum in my tank when I open
the cap(non vented) Is this supposed to have a vacuum with a non vented
cap.I could put the truck in the garage and check for sure if need be. let
me know!           Jim
