1970 Duster Filler Neck Replacement

When you get your filler neck, a couple of suggestions:

Leave the tank loose as you try to get the filler neck in place - these ones where the tube goes in from the inside of the trunk (as opposed to others that install from the outside of the body) can be cantankerous.

Don't freak when you figure out that the little vent tube just goes into your frame rail and ends - that's the way they were designed. Many of the seals for the trunk floors come without the vent tube hole opened up and you just have to do that yourself.
