    Hey everyone, hope someone here has already come across this and can help me out. My 70 R/T didn’t have a fuel filler tube in it when I got it. Installed a new AMD trunk pan and didn’t realize it doesn’t have the hole for the vent tube pre drilled. I’m pretty sure it’s 7/8 in diameter, does anyone have any measurements on where exactly to drill it?

    I'm confused as to what you mean. As I stated in the PM, NO 1970 Charger that I know of had a vent line on the filler neck.

    Those rubber plugs have no vent line going through them. Are these the holes you're thinking of?
    The 1970 had a different vent system different from that 1/4" line that other cars had alongside the filler neck.

    I think it's that fwd rubber grommet in your top pic. The vent tube angles straight down from the filler tube a few inches from entering the gas tank. It vents in the frame rail if I remember right.

    Only California 1970 Chargers got the vent tube monstrosity setup on the passenger side.

    That’s great if it doesn’t, that way I don’t have to drill a hole in the painted floor. In your first pic there’s 2 rubber plugs to the left of the filler neck opening. The top one has a hole in it, that’s where I assumed the vent line went. Does anything actually go through it?

    Those pictures are of my project car, Jigsaw. It is a California car.

    Great thanks for the photos Kern Dog and Ray70Chrg, looks like the 2 grommets are close enough to almost touch. Should be able to figure out location to drill the hole from them.

    Holy crap....I have never seen a vent line on any 68-70 Charger.
    Sorry that I was so rude, I didn't think that this was an actual thing that they did!
