RPM Kawasaki Teryx H2 6.8 Gallon Auxiliary Fuel Tank

Maximize your adventure time with the all-new RPM Kawasaki H2 6.8 Gallon Auxiliary Fuel Tank, purpose-built for the supercharged Kawasaki Teryx H2. This drop-in tank installs cleanly into the factory empty space under the passenger side rear seat, delivering a massive boost in range without sacrificing comfort or performance.

Includes a precision billet fuel fill adapter that seamlessly converts the OEM Kawasaki fill cap to a durable Kelch click-style cap. A fluorolined silicone hose connects between the factory fill neck and the supplied cap, integrating both the fill tube and breather into the main tank for effortless operation.

Installation is incredibly simple and completely non-invasive — no cutting, no modifications to the OEM fuel tank, chassis, emissions components, wiring, or battery relocation. All fuel lines route safely away from drivetrain parts, and both seats remain fully functional.

Constructed from rugged 5mm rotomolded plastic, this tank is engineered to withstand the harsh abuse of dunes, trails, and desert running. It ties directly into the factory fill neck for filling and venting, so there’s zero hassle and no annoying fuel fumes in the cab — a common issue with other kits.

Every RPM kit comes complete with:

High-flow pump delivering 1.25 GPM (significantly faster than most competitors)
Plug-and-play wiring harness with a convenient momentary switch (prevents accidental pump run time or burnout)
All necessary fittings, hardware, and clear step-by-step instructions

Safety remains our top priority. If you overfill the main tank, excess fuel automatically routes back to the auxiliary tank via the vent line, ride with total peace of mind.
