Default Rubber Gasket on your gas cap!?

So, the subie is about to hit 170k and lately I've noticed an intermittent CEL.. The rubber gasket on the gas cap has a large crack in it.

I was wondering if anyone had managed to source a good replacement gasket. I'm not terribly thrilled with giving SOA $40 for a new cap when all I need is a cheap rubber gasket.

Any ideas?

Get one from an autoparts store. It's a gas cap, as long as it's sealed it's fine.

I know but, my wife drives the car most of the time and if the cap isn't tethered to the car it may not make it home...

Buy one of those o-ring kits, comes with different sizes, and find one thats nice and fat, stretch it and make it fit.

The generic gas caps offered at parts stores do not have the indented "sleeve" whereby to affix the tether that comes with the stock wrx. Another friend of mine has tried this.

I considered buying a generic o-ring set but it has to be fuel resistant and of certain thickness.. I know they are out there and I'll eventually track one down but I was just asking because it's a relatively common problem to have the o-ring crack and kick off a CEL..

I can't believe that people would be ok with paying SOA $40 for a stupid gas cap.

How about $50 for a rubber valve cover gasket?

Google those o-ring companies and ask for a viton o-ring for the size you need.

post in the want to buy section.
I think there will be someone selling you the cap or the gasket.
Mention the price new and what you're willing to pay.
A gasket can go in an envelope and may only require an extra stamp for postage.

I thought I read that the fuel pump gasket could also be a culprit.
