    Default Leaky Fuel Cap? Fix?

    I've noticed gasoline smell around the gas cap, even when the car has been parked for a week or more. Where can I buy a new gas cap (2010 Rossion, RUS#56)? Or do I simply replace the o-ring that is on the inside of the gas cap? Does anybody know what size o-ring it is? Thanks.

    I think it's using MOCAL: http://50.62.235.225/files/cap.pdf
    raidenperformance.com seems to have them listed.
    similar one also here: http://www.tanksinc.com/index.cfm/pa...rod/prd566.htm

    Also, check for fuel leaks elsewhere in the engine bay, around the fuel tank. But given the fact the Rossion fuel tank is vented outside (just follow the vent line, through the filter...), I have my doubts you can get rid of the "gas perfume" completely.

    Newton is the supplier of the caps

    https://www.newton-equipment.com/aer...iller-cap.html

    Also interested if they sell just the o-rings

    Measure up the old o-ring, buy it from here:

    It's what I used for replacement oil-relocation kit o-rings.

    Try tightening the nut on the bottom of the cap a little, like a quarter turn or so, to make it lock down a little tighter...
