Gas Cap Gasket Features and Benefits:
- Individually sold to complete one Mustang
- Direct-fit replacement
- High-quality reproduction
- High density foam composite
- Doesn’t dry and crack
- Locks in gas fumes

This is a direct replacement foam gasket that seals the gas cap to the filler pipe and keeps fumes from escaping. This is a recommended part to purchase when updating your fuel system because this gasket is much better quality than the original factory one. The standard cork fittings tend to dry-out and crack over time, but this gasket made of high-density foam will not dry or crack and will keep all gas fumes inside the tank.

CJ Pony Parts has all the parts you need to bring your early model Mustang build back to life--browse our huge selection of restoration parts for your pony today!

Rated 5 out of 5 by from Fits great. I purchased this gas cap gasket to replace the original cork/ rubber gasket that was only about half there. It leaked and allowed the cap to be loose. The new gasket went on with no problem and has solved the problems.

Rated 5 out of 5 by from should have gotten one of these years ago I did not realize this item was available. My '67 gas cap has always been loose and I figured I needed a new one. Well, after reading a review from some other purchasers who took the time to post their experience, I bought one. Just stretch the rubber over the engagement tabs and it pops into place. Not sure how long this will last but for under $3 delivered, I'd be happy to buy one every few years.

Rated 5 out of 5 by from Works exactly as it should For months I always had a lingering smell of gas in my garage and had finally narrowed it down to a disintegrated gas cap gasket. I thought I would have to buy a new gas cap just for the gasket but when I found the gasket only it made sense to buy this since my current gas cap is in perfect condition. After it arrived I installed it in seconds and the smell of gas disappeared.

Rated 3 out of 5 by from Still leaks fumes I have a lot of gas fumes in the garage when all the doors are shut. I looked at my gas cap and sure enough the gasket was worn out. I replaced the gasket and it got worse. The thickness doesn't appear to be the same and I think that may be the problem.

Rated 5 out of 5 by from It Fits! When I saw this in the packaging I said to myself "No way this thing will fit." And yet it did after a white knuckle experience stretching it over the tabs on the cap. Seems to work very well

Rated 5 out of 5 by from Very nice i purchased one of this and install it on top of the old seal to make the gas cap tighter and seal good. No more fumes smell emmiting out of my gas filler.

I need a replacement gas cap gasket for a 1956 Ford F100. Don’t want to buy a new cap just need the gasket. Was wondering if the gasket for the mustang would work on my cap.

on a std stock 1965, does this gasket prevent the gas tank/ gas cap from venting?

This seals the gas cap to the filler pipe and keeps fumes from escaping.
