Gas Cap Gasket, gas cap Options

[Mike1981]

Hello Everyone

I tried to use the search function on this but was unsuccessful...

My gas cap gasket seems to have failed, and leaks when tank is full and I turn hard.

I have a metal cap with a cork gasket.

Does anyone know where I could buy a new one?

Thanks

First - stop overfilling the tank

Second route hoses properly.

Orange is overflow - route out holes below tank to ground

Green is supposed to go to the vapor expansion tank and then to charcoal canister

Looking at your blue tank I can only assume that you no longer have the expansion tank, charcoal canister, and associated plumbing back to the engine.

Route green line same as orange if need be. You will have vapor / smell until you route to a charcoal canister which gets purged at each drive.

Place WTB ad on classified forum - plenty of caps floating around out there.

Thanks Superhawk for the advice.

Yes charcoal canister is long gone. So Tie both together and route down to hole below tank?

I wouldn’t worry about trying to tie together into a common line if that’s what you mean. Just route both under car.

If you park outdoors you’ll be fine.

If you’re parking in a garage you should look into finding the expansion tank and charcoal canister. I had to go this route - like your car, mine came to me “fixed” by DAPO who got rid of the evap system when they installed carbs. (IMG:style_emoticons/default/chair.gif) Full disclosure: I was a DAPO back in the 80s with my first 914 and ditched the evap stuff when I went to carbs . . . And dealt with occasional gas smells.

For what it’s worth, by having tank vented to atmosphere, it’s not great for the environment and over time your most volatile parts of gasoline evaporate off which I’d rather be burning and making power with instead of smelling up the garage.
