Minimum Fuel Pump Flow Calculator

The Minimum Fuel Pump Flow Calculator helps determine the minimum fuel pump flow rate required for an engine, based on the estimated maximum horsepower and the Brake Specific Fuel Consumption (BSFC) of the fuel or application. This calculation is crucial to ensure the engine receives the correct amount of fuel, thereby preventing fuel starvation and maintaining optimal performance.

By inputting the estimated maximum horsepower and BSFC into the Minimum Fuel Pump Flow Calculator, users can obtain the minimum fuel pump flow rate in both gallons per hour (GPH) and liters per hour (LPH). To compute the Minimum Fuel Pump Flow Rate in GPH, multiply the estimated maximum horsepower by 0.8, then multiply the result by the BSFC fuel rate, and divide by the pounds per gallon of fuel. To convert GPH to LPH, simply multiply the result by 3.785.

This tool is especially beneficial for performance tuning and engine upgrades, enabling users to align the fuel pump capacity with the engine's demands. Properly sizing the fuel pump is essential for the efficient and reliable operation of the engine under all conditions.
