A performance fuel pump is designed to deliver higher flow rates and pressures compared to stock fuel pumps. If you've upgraded your engine or increased its power output, a performance fuel pump ensures that your fuel system can keep up with the increased demand. While a performance fuel pump can be installed in stock vehicles, it is typically overkill unless you're planning future upgrades.
The primary difference lies in the flow rate. A 255lph fuel pump can deliver 255 liters of fuel per hour, while a 340lph fuel pump can deliver 340 liters per hour. Higher flow rates, such as those provided by the Walbro 255 fuel pump or the Hellcat fuel pump, are ideal for engines that require more fuel, especially in high-performance or forced induction applications.
Yes, many high flow fuel pumps are compatible with E85 fuel. However, not all pumps are E85-safe, so it's important to choose a pump specifically designed for ethanol fuels. Check the descriptions and specifications for the pump you are considering to ensure its E85 compatibility. These pumps are built with materials that withstand the corrosive properties of ethanol.
When selecting a high pressure fuel pump, you should consider your vehicle's horsepower, fuel type, and engine modifications. For example, a 255lph fuel pump is a great choice for moderate horsepower builds, while a 340lph fuel pump is better suited for higher horsepower applications. Additionally, if you're using E85 fuel, ensure the pump is ethanol-compatible. Consult our guide for more information on choosing the right fuel pump for your horsepower goals.
A 255 fuel pump provides a higher flow rate than most stock pumps, making it ideal for performance upgrades. It's capable of supporting up to 500 horsepower on gasoline and is a popular choice for both naturally aspirated and turbocharged engines.
The main difference is location: an external or in-line fuel pump is mounted outside the fuel tank, while an in-tank pump is located inside. External pumps are easier to access and replace, making them a popular choice for high-performance or custom setups, such as when using a universal fuel pump.
Quantum Fuel Systems offers a full line of performance fuel pumps from their own brand (High Flow Fuel Pumps) but they also carry AEM, Bosch, and Walbro fuel pumps.
The fluid you may find in your new Quantum fuel pump is testing fluid used during the manufacturing process to ensure the pump operates correctly under real-world conditions. We test pumps with fluid to check for proper flow, pressure, and functionality. This fluid is harmless and will not negatively affect your fuel system. It's completely safe to install and operate a pump that contains residual testing fluid.
