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/application.

This calculation is essential for ensuring the engine receives the correct amount of fuel, preventing fuel starvation, and maintaining optimal performance. By inputting the estimated max horsepower and BSFC, the calculator provides the minimum fuel pump flow rate in both gallons per hour (GPH) and liters per hour (LPH).

To calculate Minimum Fuel Pump Flow Rate in GPH, you take the value of the estimated max horsepower times 0.8 then multiply it by the BSFC fuel rate divided by the lbs per gallon of fuel

To convert GPH to LPH, you just multiply the result by 3.785.

This tool is particularly useful for performance tuning and engine upgrades, allowing users to match the fuel pump capacity with the engine's requirements. Properly sizing the fuel pump ensures the engine runs efficiently and reliably under all conditions.
