When it comes to keeping your Polaris XP 1000 running at peak performance, the fuel pump isn’t a part you can afford to overlook. This high-output UTV demands a pump that matches its 110-horsepower engine and 14.5-gallon fuel capacity, especially if you’re tackling rough trails or pushing speeds over 80 MPH. The stock fuel pump, part number 2874038, delivers a flow rate of 50 gallons per hour (GPH) at 40-60 PSI, which works well for casual riding. But if you’ve upgraded to a turbo kit or regularly operate in extreme conditions—like desert racing or heavy mud—you’ll need an aftermarket solution to avoid fuel starvation.
One popular upgrade is the Fuel Pump from Kemso Racing, designed specifically for high-performance applications. Their 340LPH (liters per hour) model provides a 30% increase in flow compared to stock, ensuring consistent pressure even during prolonged wide-open throttle. This pump also features a brushed DC motor with a lifespan of 15,000+ hours, nearly doubling the durability of OEM components. For riders who’ve experienced engine sputters at 6,500 RPM or higher, switching to this unit often resolves issues caused by inadequate fuel delivery.
The importance of proper fuel pressure became clear during the 2022 Baja 1000, where multiple Polaris XP 1000 teams reported engine failures linked to stock pumps overheating in 100°F+ temperatures. Post-race tear-downs revealed collapsed internals and worn brushes—failures avoided by teams using reinforced aftermarket pumps. Kemso’s design incorporates a thermal-resistant housing rated for -40°F to 302°F, making it reliable whether you’re ice-riding in Minnesota or dune-bashing in Glamis.
Installation is straightforward for most DIYers, taking 2-3 hours with basic tools. The kit includes a pre-assembled module with a 100-micron stainless steel filter, bypass regulator, and OEM-style connectors. At $189.99, it’s 25% cheaper than Polaris’ replacement pump while offering better performance—a no-brainer for budget-conscious riders. Just remember to check your fuel line diameter (standard is 3/8”) and electrical connectors (Metri-Pack 150 series) before ordering.
So, does upgrading really make a difference? Ask Colorado-based off-road racer Jenna Carter, who shaved 8 seconds off her hill-climb times after installing the Kemso pump. “Before, my RPMs would flatline halfway up steep inclines,” she says. “Now the throttle response feels instantaneous, like the engine’s finally breathing properly.” Whether you’re chasing podium finishes or just weekend adventures, pairing your XP 1000 with the right fuel pump ensures you’re getting every drop of power from that ProStar engine.
