RPM RZR Pro XP, Pro S, Turbo R 3.8 Gallon Auxiliary Fuel Tank

RPM RZR Pro XP, Pro S, Turbo R 3.8 Gallon Behind-the-Seat Auxiliary Fuel Tank

Don't let a low fuel gauge cut your ride short. Range anxiety is officially a thing of the past with the all-new RPM SxS Behind-the-Seat Auxiliary Fuel Tank for the Polaris RZR Pro XP, Turbo R, and Pro S!

We know how it goes—you’re miles deep into the trail, the foot is heavy, and the fuel light starts flashing. We designed this 3.8-gallon tank to keep you out of the pits and on the gas longer. Constructed from ultra-durable, rotomolded plastic, this tank is built to take the exact same off-road abuse your Pro XP does. It tucks perfectly behind the seat, maximizing your cab space without getting in the way of your ride.

We hate piecing kits together just as much as you do, so we made sure this one is a 100% complete system. Every tank ships with a dedicated fuel pump, a complete wiring harness, and all the heavy-duty mounting hardware you need. We even bulletproofed the operation: the kit features a momentary dash switch for fuel transfer, meaning you can never accidentally leave the pump running. This completely eliminates the risk of pump cavitation or overheating. No guessing, no burned-up pumps, no extra trips to the parts store—just bolt it in, wire it up, and get back to the dirt.
