RPM RZR Pro R 2-Seat 4 Gallon Auxiliary Fuel Tank

Maximize your ride time with the RPM RZR Pro R 2-Seat 4 Gallon Auxiliary Fuel Tank. Specifically engineered to fit the 2022–2025 RZR Pro R 2-seat models, this RPM fuel tank adds 4 gallons of auxiliary capacity without sacrificing cabin space or comfort.

Constructed from 4mm thick aluminum and TIG welded for superior durability, this auxiliary fuel tank mounts securely behind the driver’s seat using factory chassis points and stainless brackets. Designed for rugged use, this RPM fuel tank increases your overall fuel supply by nearly 50%, ensuring extended off-road adventures without interruption.

The smart design allows OEM seat adjustments to remain fully functional, so you maintain full legroom and sliding seat capabilities. The system connects seamlessly to your factory fill neck and vent line, preventing in-cabin fumes and allowing quick, hassle-free installation. It uses a high-volume fuel pump that transfers at 1.25 GPM—outpacing competitors—and a plug-and-play wiring harness with a momentary switch to prevent accidental activation.

Safety is paramount. Unlike other designs, the RPM RZR Pro R auxiliary tank uses the OEM tip-over check valve for rollover safety and routes overflow back to the main tank, eliminating fuel spill concerns.

Features:

  • 4-Gallon Capacity
  • Ultra-Durable 4mm Aluminum Construction
  • Plug-and-Play Wiring Harness with Safety Switch
  • Factory Seat Position Maintained – No Legroom Loss
  • OEM Fill Neck & Vent Compatibility
  • Fast-Flow 1.25 GPM Fuel Pump
  • Rollover-Safe OEM Tip-Over Check Valve
  • Includes All Hardware, Fittings & Detailed Instructions

Fitment:

  • RZR Pro R 2-Seat Models: 2022–2024
  • RZR Pro R 2-Seat Sport & Ultimate (2025) – Only without OEM seat harnesses

Upgrade your RZR Pro R fuel system with the RPM 4 gallon auxiliary tank and enjoy longer, safer, and more confident trail runs.
