RPM Speed UTV El Jefe 12 Gallon Auxiliary Fuel Tank
Extend your range and conquer multi-day desert adventures, long-distance Baja pre-runs, or epic dune sessions without fuel anxiety! Designed by RPM Powersports specifically for the 4-seat Speed UTV El Jefe, this 12-Gallon Auxiliary Fuel Tank Kit delivers the extra fuel capacity you need for all-day, hammer-down riding.
Crafted from heavy-duty 6mm thick seamless rotomolded plastic, this rugged auxiliary tank is custom-engineered to mount low under the factory seats. By positioning 12 gallons of fuel at the lowest possible center of gravity, it maintains crisp handling dynamics and eliminates top-heavy body roll in high-speed turns. When your primary fuel level gets low, simply flip the dash switch—the integrated high-flow electric pump transfers fuel directly into your main factory tank at a rapid 1.2+ GPM.
Safety and convenience are built into every detail. The system integrates cleanly into the OEM breather system using the factory tip-over check valve to prevent fuel spillage during a rollover. An automated fuel loop prevents accidental overfilling by returning excess fuel back to the auxiliary tank once the main tank is full. Installation is completely non-invasive with zero cutting, welding, or chassis modifications required.
Features:
-
12-Gallon Fuel Capacity Increase: Substantially extends operating range for long-distance trail rides, desert racing, and remote dune runs.
-
Low-CG Under-Seat Mounting: Mounts securely under the factory seats to keep fuel weight low, preserving machine stability and cornering balance.
-
Heavy-Duty Rotomolded Construction: Seamless 6mm thick rotomolded plastic body withstands severe off-road vibration, impacts, and rough terrain.
-
High-Flow 1.2 GPM Transfer Pump: Rapidly pumps fuel into the primary tank on the go with minimal wait time.

Safe Momentary Switch Operation: Includes a plug-and-play wiring harness and momentary dash switch to prevent leaving the transfer pump running unintentionally.

Integrated Rollover & Anti-Overfill Safety: Ties into the factory tip-over check valve for rollover protection, with a built-in overflow loop that safely returns excess fuel to the aux tank when the main tank hits full.
-
100% Bolt-On Installation: Custom brackets and hardware secure to existing mounting locations—no cutting, drilling, or chassis welding required.
-
