Extend your range and fuel up your adventures with the RPM 4-Gallon Auxiliary Fuel Tank for all Polaris RZR Pro XP 2-seat models. This premium tank utilizes unused space behind the passenger seat, giving you nearly 50% more fuel capacity without compromising comfort or altering any factory seat adjustments.
Crafted from ultra-durable 4mm thick aluminum and fully TIG welded, this tank mounts directly to the OEM chassis mounting points, with added stainless steel bracketry for rock-solid installation. The system uses the factory fill neck and vent system, so there's no in-cab fuel fumes, no need to reroute wiring, and no fuel lines running near drivetrain components.
Included is a plug-and-play wiring harness with a momentary switch that prevents pump overrun, even if installed in dual-tank setups. The high-volume fuel pump delivers 1.25 gallons per minute, significantly outpacing typical auxiliary fuel systems.
