Can I run race gas with a KEMSO Fuel Pump?

If you’re a performance enthusiast or someone who pushes their vehicle to the limits, you’ve probably wondered whether your fuel system can handle race gas. Specifically, if you’re using a Fuel Pump from KEMSO, you might be asking: “Can I safely run race gas with this setup?” Let’s break this down in a way that’s practical and grounded in real-world experience.

First, let’s clarify what race gas actually is. Race fuel, or racing gasoline, is a high-octane fuel designed for engines operating under extreme conditions. It’s commonly used in motorsports, track days, or high-performance builds where standard pump gas doesn’t provide enough knock resistance or stability. Race gas often has additives or blends that help engines perform at their peak—but not all fuel systems are built to handle it.

Now, KEMSO fuel pumps are popular in the aftermarket scene for their reliability and ability to support higher horsepower applications. These pumps are engineered to deliver consistent fuel flow, even under demanding conditions. But does that mean they’re compatible with race gas? The short answer is yes—but there are a few important considerations.

**Material Compatibility Matters**
Not all fuels are created equal, and race gas can vary widely in chemical composition. Some blends contain higher levels of ethanol or methanol, while others might include aggressive detergents or oxygenators. The good news is that KEMSO pumps are designed with materials that resist corrosion and degradation from most racing fuels. The housings, seals, and internal components are tested to withstand harsh chemicals, which means you’re unlikely to face issues like swelling or leaks. However, it’s always wise to cross-check the specific race fuel you’re using with the manufacturer’s recommendations. If you’re running something unconventional, like methanol or nitromethane, you’ll need to confirm whether your pump is rated for it.

**Flow Rates and Pressure Requirements**
Race gas doesn’t inherently change how a fuel pump operates, but your engine’s demands might. When you switch to race gas, you’re often doing so to support a more aggressive tune, higher boost levels, or advanced timing—all of which require precise fuel delivery. KEMSO pumps are known for maintaining steady pressure and flow rates even at high horsepower levels, which is critical for preventing lean conditions or fuel starvation. That said, always ensure your pump’s capacity aligns with your engine’s needs. If you’re pushing 800+ horsepower on E85 or a similar blend, you might need to upgrade to a higher-flow model or consider adding a secondary pump.

**Temperature and Longevity**
Race gas can sometimes run hotter than standard pump gas, especially in forced-induction setups. While KEMSO pumps are built to handle elevated temperatures, prolonged exposure to extreme heat can affect any component. Make sure your fuel system is properly insulated and that the pump isn’t sitting in a high-heat area of the vehicle. Regular maintenance checks are also a must. Inspect the pump for signs of wear, listen for unusual noises, and monitor fuel pressure data if your setup includes a gauge or sensor.

**Tuning and Safety**
Even if your pump is compatible, running race gas without proper tuning is a recipe for disaster. Higher-octane fuels allow for more aggressive timing and boost, but your ECU needs to be calibrated to take advantage of these properties. A mismatched tune can lead to incomplete combustion, fouled spark plugs, or even engine damage. Always work with a qualified tuner who understands your fuel and setup. Additionally, keep in mind that race gas has a shorter shelf life than regular gasoline. If you’re not driving the vehicle frequently, consider adding a stabilizer or draining the tank between uses.

**Real-World Feedback**
Many users in racing forums and communities have shared positive experiences using KEMSO pumps with race gas. For example, drag racers running 100+ octane fuels report consistent performance during passes, while track-day drivers praise the pump’s reliability during extended sessions. Of course, results vary based on the overall build quality of the fuel system—things like injectors, lines, and filters all play a role. Pairing a KEMSO pump with quality components ensures a seamless experience.

In summary, yes, you can run race gas with a KEMSO fuel pump—as long as you’ve done your homework. Verify material compatibility, ensure the pump’s flow rate matches your power goals, and prioritize proper tuning and maintenance. Racing fuels open the door to incredible performance gains, but they also demand attention to detail. By taking these steps, you’ll maximize both safety and power, whether you’re chasing lap times or dominating the drag strip.
