My 72 240 large mouth gas cap has a chain hooked to the inside of the cap. Where on earth does the other end hook too? Can't seem to come to a logical conclusion.

Thanks!

It links to the inside of the filler tube. I can't recall exactly where the loop is for it, but I think it's toward the bottom of the opening.

There should be a 1" dia. double ring (split ring, key chain type) on the chain to the hole in the inside of the filler ring. Filler ring may need to be removed to install, place ring with chain at the bottom.

I don't have the inner ring, but even at that, I can't find a place to attach it if it were thre. I was wondering if there was a spring loaded "bar" that worked like a t bar or something. My other widemouth car has nothing at all so can't compare it. My FSM is on loan to a buddy but not sure it would show it anyway.

Mine is still attached, but I don't have any pictures and didn't drive the car to work today. But both Steve and Bonzi are correct, there should be a hole on the inside lip of the filler flange for the chain to attach to.

Yup, a small hole about 1/16" diameter in the filler neck shoulder.

Leonard,

Here are a couple of photos from an old filler tube from my 76 280Z.

A picture is worth a thousand words! This I can figure out:D

Many thanks!
