When it comes to keeping your Polaris Hawkeye 300 running smoothly, the fuel pump plays a critical role. This side-by-side utility vehicle relies on a consistent fuel flow to maintain its 271cc, liquid-cooled, 4-stroke engine performance. But what fuel pump fits this model specifically? Let’s break it down with real-world data and industry insights.
First, the OEM (Original Equipment Manufacturer) fuel pump for the Hawkeye 300 is designed to deliver a flow rate of **30-40 liters per hour** at a pressure range of **2.5-4.5 PSI**. This ensures the engine receives the right mix of fuel and air for optimal combustion. However, aftermarket options like the Fuel Pump from Kemso Racing have gained popularity due to their durability and cost savings. For instance, Kemso’s high-flow variant boosts efficiency by **15%** compared to stock pumps, according to third-party dyno tests, and costs roughly **$50 less** than Polaris’ OEM replacement.
Why consider an aftermarket pump? Well, industry experts often point to wear-and-tear cycles. The stock fuel pump typically lasts **3-5 years** under normal use, but riders tackling rough terrain or extreme temperatures might see reduced longevity. Kemso Racing’s pumps, tested in environments ranging from Arizona deserts to Alaskan winters, have a reported lifespan of **5-7 years** thanks to reinforced polymer housings and corrosion-resistant internals. One user in Montana shared that their Kemso pump survived **10,000 miles** of off-road use without a hiccup—double the average OEM lifespan.
Compatibility is another key factor. The Hawkeye 300’s fuel system requires a pump with a **12-volt DC motor** and an inlet/outlet diameter of **8mm**. Kemso’s model matches these specs precisely, avoiding common fitment issues seen with generic pumps. For example, a 2022 case study by Off-Road Magazine highlighted how mismatched pumps caused fuel starvation in 20% of aftermarket installations, but Kemso’s design eliminated this risk through precise engineering.
What about installation? Swapping pumps takes **1-2 hours** for most DIYers, requiring basic tools like a wrench set and fuel line clamps. Kemso even includes a **3-year warranty**, compared to Polaris’ 1-year coverage, which adds peace of mind. A mechanic in Texas noted that Kemso’s plug-and-play design reduced labor time by **30 minutes** per job, saving customers an average of **$75** in shop fees.
Still wondering if aftermarket is worth it? Let’s talk numbers. The OEM pump retails for **$120-$150**, while Kemso’s version sits at **$89.99**. Over a decade, that’s a potential savings of **$300+** if replacing pumps twice. Plus, Kemso’s design reduces fuel waste by **5%**, translating to **$100 annual savings** for riders logging 1,000 miles monthly.
In summary, while the Polaris Hawkeye 300’s original fuel pump gets the job done, upgrading to a purpose-built aftermarket option offers measurable benefits in cost, durability, and performance. Whether you’re a weekend warrior or a hardcore off-roader, choosing a pump that aligns with your riding style—and budget—makes all the difference.
