Leaky gas cap

[jrigheimer]

I have been having problems with my gas cap, it's not major like gas pouring out, but more like gas drips down the side and I have to wipe it up. I think it's a non original gas cap but I also have the slant 10571 and it does lock or seal if I thighen it all the way. Any one have any temporary fixes and what cap should I get, has to be locking

I had the same problem and could not find a cap to work with my 72. I finally added a second cap gasket and it solved my problem seals great now.

I stuffed an o-ring under the gasket on my cap to tighten the seal. Works well so far.

The inner lip that has a ( I'm at a loss for words) cam type taper to it has over the years pulled outward so its getting closer to level with the outer edge of the gasket surface. I took a piece of hard wood dowel ( I would have prefurred a brass drift pin or dowel but didn't have one), and began by putting the dowel on the inner edge of the filler neck and tapping it with a hammer slowly working my way around the neck till the gas cap felt right when putting it on. DONT USE METAL, STEEL OR ANYTHING THAT COULD CAUSE A SPARK! Just 2 cents, it worked for me...

Was just noticing the other day on LMC, I think there are 3 different applications. C20, and 2 different year ranges. The locking is for only 1 of those apps.

For the Stant cap. I think I tried 3 or 4 different part numbers and none of them fit well. I removed one of the gaskets from on of the Stants and used it. You should be able to pick one of these caps up from you local Auto Zone, NAPA, etc for $5-$7.
