    Tusk Billet Aluminum Gas Cap, Clarke Fuel Tanks

    Michael in NY

    Not all clarke tanks

    Clarke changed their thread measurement at some point and so this cap didn't fit my old style Clarke tank. However Rockymountain was understanding and allowed me to return no problem. But I don't think the listing in the catalog has been changed.

    Leaks on one but not on another ?

    Leaked and caused staining to my IMS tank. Tried it on my CLARK tank and it works great. Must be marked wrong.

    Looks better than stock

    The cap spins on/off easily, looks sweet, and does not leak when riding my '09 Raptor. It will constantly drip all over your quad if you stand your quad vertically (like inside a trailer). If you have to stand your quad up, you will have to put your OEM cap back on.

    GOOD LOOKING GAS CAP!

    Adds that finishing touch. Fits my Polaris 800 Sportsman & my 850 sportsman. Got one for each bike. Even though they tell you it's for SXS it fits my ATV'S like the stock ones, but much better looking

    CLARK plastic gas cap

    What a piece of junk. Bought a Clark dezert tank that came with it. Tank is very nice but cap lasted about three months and then split in half right where it says Clark. Had to buy a billet one.
