Pro R, Turbo R, Pro XP 4 Seat 7.5 Gallon Floor Board Fuel Tank
Expand your long-distance range without sacrificing permanent interior space or compromising safety with the RPM SXS Floorboard Auxiliary Fuel Tank System! Specially engineered to sit snugly in the rear floorboard of 4-seat Polaris Pro-series machines, this auxiliary tank secures firmly to the chassis using the factory folding seat bracket paired with our custom J-clamp mounting hardware. Need extra legroom or temporary cargo space? The entire unit can be removed in minutes—simply cap the fill fitting with the included cover and unclamp.
Configurable as a single tank or a dual-tank setup (utilizing both rear floorboards), this system ties directly into the factory filler neck for both refueling and venting, completely eliminating fuel smells inside the cab. Safety remains paramount: the system preserves the OEM tip-over check valve to prevent fuel spillage during a rollover, and an automated recirculation vent automatically routes any main-tank overfill back into the auxiliary tank. Powered by a high-volume 1.25 GPM pump, it transfers fuel fast via a plug-and-play wiring harness with an inline momentary switch—preventing dry-running, pump burnouts, or accidental activation. A single switch effortlessly controls both single and dual-tank configurations for a clean, streamlined dash setup.
Features:
Removable Floorboard Design: Drops snugly into the rear floorboard and secures via factory seat brackets and supplied heavy-duty J-clamps for rapid installation and quick removal.
Single or Dual Tank Capability: Run a single tank (passenger side recommended) or install tanks in both rear floorboards for maximum fuel payload.
1.25 GPM High-Volume Fuel Transfer: High-output pump rapidly transfers fuel into the main tank to minimize downtime.
Plug-and-Play Wiring & Momentary Switch: Pre-wired harness with a safety momentary switch prevents leaving the pump running accidentally; one switch manages single or dual setups.
Zero Cab Fuel Fumes: Taps into the OEM filler neck for refueling and ventilation, keeping 100% of gas vapors outside the cockpit.
Non-Invasive Installation: Zero cutting into chassis steel, zero battery or wiring relocations, and zero fuel lines routed near rotating drivetrain components.
Advanced Rollover & Overfill Protection: Retains the factory tip-over safety valve and features automated overfill recirculation back into the auxiliary system.

Instructions were easy to follow. Installation was not bad if you have the time to sit and install it with a couple modifications was able to remove tanks within about 10 minutes if you need the space for passengers.
Great quality. Pretty easy install. As you can see I had to use two metal bands in place of the provided clamp to hold it in place as the bolts on the clamp provided weren’t long enough. I like this option better though so all in all very happy.
The auxiliary fuel tank did everything I needed. A couple small tweaks on the install along with the detailed directions and it took a few hrs with help from a buddy. We took the 2024 Pro R 4 ultimate from Ensenada to San Quintin on the beach with no problems. 150 range with the car now and no issues. Would definitely recommend 🍺🍺🍺🍺🍺
Install was pretty straightforward….instructions were easy to follow. The craftsmanship of this tank was flawless. The tank will allow us to extend our adventures.
I am extremely happy with the RPM Pro R 4 floorboard fuel tank. The kit is aircraft quality. They include everything you need. Installation was straight forward.
Now I have a 150-160 mile range.
FYI, if you want to run the wiring inside the console, do that first because you can't remove the console with the fuel tank in place on a Pro R 4.
Overall it works as advertised and I am happy. The fitment is on point and the build quality is there. The only reason I gave 4 stars is because the return line was longer than needed and it caused one of the fittings to snap off. I ended up going to an automotive hose store for a replacement for $25 because I was in a hurry.
Love the tank. Easy to install tank, running wiring to dash is not fun getting all the console out and back in place isn’t fun. . Install video would be great. Game changer on long rides. No more gas bags or jugs.
Very nice tank kit! Beautiful tank that fits like a glove in passenger floorboard. Well-thought out pump and fittings. Two minor things: vent hose is a bit too long, necessitating spiraling it around the fuel line; and the power plug for the Polaris accessory bus bar needs the relay to be re-wired to the bottom B+ position of the plug. Minor in the bigger scheme, which is safe, convenient storage of additional fuel.
The install of this RPM product is a breeze! I was worried a bit due to having a rear bench but it still works with some minor modifications have to make a bracket to hold it down in lieu of the seat base.
Very happy with the tank including the quality and shipping . The package was received in perfect shape and in a timely fashion.
Very pleased and will buy from them again.
I called after hours on a Saturday and a great guy picked up the phone when he didnt have to and helped me with a great amount of knowledge .
