Looking for a gas cap for my 2011 EC 300

I looking for a gas cap for my 2011 EC300.

Somehow the rubber piece under the cap got deformed and now won?t seal.

I cut a piece of 1/8" cork to add to my existing rubber gasket to deal with the leaking, and it worked perfectly. I found that the outside shoulder of the cap hit the recess shoulder of the tank before the gasket seated. The extra 1/8" worked perfectly. Maybe try some 1/4" or two layers of 1/8" cork to replace or supplement your rubber gasket.

Edit: I had a 2011 EC300 as well.

I recently bought a new gas gas gas cap from www.gasgaspartsguy.com

I have a spare one. There was an updated cap and an older one. In the end I simply pulled out the seal and found for all purposes the plastic on plastic seals well enough.

Thanks guys, I’m going to try pulling the rubber out and replacing it with a cork seal

We have a lot of steep climbs and descents here and on my last ride I had a pretty constant smell of raw gas and a muddy mess around the cap.
