fuel neck for challengers

[clonewars]

Is the same design of the fuel filler the same through 70-74??

There are some differences depending if the car has emissions or not.

70 was unique as usual & N96 emissions as well

The 70 had the little nipple on top, in the trunk for the vent hose that ran into the frame rail. Finding a non-vented gas cap that fits is a pain in the butt too because of the shallow cap area on the inlet hole. The depth of the locking ramps and the slot cut-out widths vary too.

A friend left his 70 cap at a gas station on the way to Carlisle 2013. We tried 9 caps from the swap meet before finding one that worked.

This might be a dumb question, but if a 70 filler tube is vented at the top, why do you need a vented cap?

'70 cap wasn't vented.

Unless California cars were, which I know nothing about.
