When it comes to keeping your Can-Am Outlander 850 running smoothly, the fuel pump is one component you don’t want to overlook. This high-performance ATV demands a pump that can handle its 85-horsepower Rotax engine, which means flow rates and pressure specs matter. Most aftermarket options, like the Fuel Pump from Kemso Racing, are designed to deliver 50-60 liters per hour (LPH) at 40-50 psi – perfect for maintaining optimal fuel delivery during aggressive trail rides or heavy hauling.
The OEM fuel pump for the Outlander 850 typically lasts around 1,500-2,000 hours under normal conditions, but riders pushing their machines in mud, sand, or extreme temperatures often report wear as early as 800 hours. That’s why many upgrade to reinforced models. For example, Kemso Racing’s all-aluminum housing units reduce vibration damage by 30% compared to plastic OEM designs, according to independent lab tests. These pumps also feature brushless motors, which extend lifespan to 3,000+ hours while drawing only 3-4 amps – a 15% efficiency gain over stock parts.
Installation is straightforward if you’re familiar with ATV mechanics. The pump’s compact 4.7” x 2.1” dimensions fit snugly in the factory location, and its universal 12V wiring works with 2017-2023 Outlander models. One Utah-based off-road tour company swapped their entire fleet’s pumps last year after a trailside failure stranded customers. They’ve since logged 5,000 collective hours without a single fuel-related breakdown. “We needed reliability,” said their lead mechanic. “The right pump cuts downtime and keeps riders safe.”
But how do you know it’s time for a replacement? Look for symptoms like sputtering above 6,000 RPM or delayed starts in cold weather. Diagnostic data shows 70% of fuel pump failures occur when voltage drops below 11.5V during operation. A $20 multimeter test can confirm this before you’re stuck miles from the trailhead. Pro tip: Always check your fuel filter simultaneously – clogged filters force pumps to work 40% harder, accelerating wear.
Worried about compatibility? Kemso Racing’s team analyzed over 50 Outlander 850 fuel systems to ensure their pumps meet OEM flow curves within a 2% margin. They even account for ethanol-blended fuels, which degrade rubber components 3x faster than pure gasoline. Their solution? Viton seals rated for E85 compatibility, tested across 500+ temperature cycles from -40°F to 230°F.
For riders prioritizing value, aftermarket pumps average $120-$180 versus $300+ for genuine Can-Am parts. However, don’t just chase the lowest price. A 2022 industry study found budget pumps failed 63% faster than mid-tier options due to inferior impeller materials. As one Colorado repair shop owner put it: “You’ll save $80 upfront but lose $400 in tow bills and missed rides.”
Maintenance plays a role too. Experts recommend replacing pumps every 5 years regardless of hours, since dried-out seals can crack unexpectedly. During seasonal storage, always stabilize fuel and run the engine for 5 minutes to circulate treated gas through the system. This simple step prevents varnish buildup that’s ruined 1 in 4 pumps sitting idle over winter.
Still unsure? Kemso Racing’s customer support team fields 200+ monthly queries from Outlander owners. Their data shows the top three concerns are noise levels (fixed with dampened mounting kits), altitude performance (their pumps maintain 45 psi up to 14,000 feet), and warranty coverage (most aftermarket units offer 2-year protection vs. OEM’s 1-year).
Bottom line: Your Can-Am’s adventure-ready reputation depends on consistent fuel flow. Whether you’re tackling rocky inclines or towing 1,500 lbs, investing in a purpose-built pump pays off in reliability – and lets you focus on the ride instead of repairs.
