Getting ready to put a new fuel pump in my 2002 T&C minivan. I've done fuel pumps on the K and cloud cars, but this is the first minivan. My factory manual says to "disconnect the fuel filler vent tube" and shows a drawing of the vent tube near the filler tube. However, my car has two large vent tubes and one slight smaller one (fuel line size), all near the filler tube. All three of these tubes pass through the frame member and then out of sight over the fuel tank. so I can't see where they go. Do I have to disconnect all three tubes? If not, which one has to be disconnected for fuel tank removal?
