ATV Gas Tanks

Has your ATV’s fuel tank seen better days? Is it broken? Do you just need a tank with a larger fuel capacity? Are you restoring an old ATV with a tank that has been ruined by gas that was never drained out? Don’t worry; you’ll find the solution to any of these problems in a new ATV gas tank from Rocky Mountain ATV/MC.

We’ve chosen to carry two brands that are renowned in the powersports industry as manufacturers of quality aftermarket fuel tanks. These two names are Clarke and IMS. Each has painstakingly developed ATV fuel tanks that have a larger capacity than stock and are designed to uniquely fit each quad. (Make sure to utilize our Parts Finder to ensure you find a tank that fits your machine properly.)

A new fuel tank will look great on your ATV, but that aspect is only secondary to being able to confidently return to the trails with a fresh tank. There’s nothing quite as nice as new equipment to replace something that isn’t quite up to par. As an ATV rider, you want to be able to get as many quality hours of riding as you can, and a new tank will help you do that. Browse our selection now.

  • IMS Fuel Tank (NO CA)

    IMS Fuel Tank (NO CA)

    Thumbs up

    The reason I ding it with four stars is because I had to order two pieces for the fuel pump from Ktm. The reason for the two new pieces is because the tank is quite a bit thinner than stock thus the other reasons for four stars. Otherwise it fits great. Has brass grommets for all plastics and the fuel pump inlaid into the plastic. I will say IMS gives you the part numbers for the Ktm parts you need directly on their website.

  • Acerbis Fuel Tank (NO CA)

    Acerbis Fuel Tank (NO CA)

    Paul in CA


    I installed a 4.1 tank on my KTM today and had a serious installation issue. The supplied petcock screws that support the fuel pump sensor plate under the seat are too short. I only got two screw threads into the plastic. Stripped one our under very very light torque. I went to hardware store and installed longer screws. I hope they work.... In my opinion the use of the supplied screws could be dangerous due to fuel leaks....

    Fit better than most after market tanks, has the largest capacity for the 17 YZ than any of the others that we found. Highly recommend!

    When you ant to get way back there on the trails, you need to get an oversized tank. It does make getting to some parts on the bike a little tough. Not cheap, but worth it.

    Really impressed , just the cap alone makes it look...

    Took me forever to find a place that would have replacement parts for Clarke aftermarket gas tanks. Glad I ran into rocky mountain atv and stocked the gas cap I needed.

  • Tusk Petcock Rebuild Kit

    Tusk Petcock Rebuild Kit

    David in AL

    Fit is Great

    This petcock kit really did the trick to stop a slow leak from my IMS tank on my YZ250. I added a little RTV on the outside of the o-ring along the flange for added protection but I don't think it was necessary. Great product and you can't beat the price!
