Gas Cap Gasket?

Anyone replace the gasket on the gas cap? I was thinking about using a flat piece of rubber, in place of the dead fiber gasket???

 

I have the same question.

 

Me three..

The rubber is cracked on the NOS cap I have on my comet...

 

Do you really need to? There isn't usually gas in the filler neck.

 

If you have a car that accelerates hard and a leaking gasket, fuel comes right out of the tank . Track officials don't like that very much, ask me how I know!

 

Yeah I can't fill my Comet, have to keep it below 3/4 tank or it dribbles out onto bumper when I punch it...

 

Must be the old wheelie problem, I guess I've been lucky, in almost 30 years of owning non stock Mavericks, and racing, I've never had this problem.

 

I also was informed by track officials dumping fuel out cap. Use a billet one with good gasket on track days now.

 

Subscribing... I would think this part would be easy to get, or a substitute for another car (mustang?) be made to work

 

well, found this on mustang unlimited site......might work.

UPDATE...... so, I just cut out a piece of rubber, about 1/16" thick, and put it on my cap. Screwed on no problem, have to see now how well it works with a full tank. That may be a while, as I am NOT driving my maverick in the snow, nope!!

 

I used rubber again on mine just made it right. Works great.

 

You guys used gasoline resistant rubber right? If not it will quickly degrade

 

I had a cap that was loose, I made a thicker gasket to remedy that.

 

The type of rubber is important, buna-n or nitrile will take the fuel. EPDM will degrade over time but considering it will not be in constant contact it will probably survive for quite some time.
