Enter your engine horsepower, fuel type, and fuel efficiency into the calculator to determine your fuel pump size.

## Fuel Pump Size Calculation Formula

The following formula is used to calculate the fuel pump size based on engine horsepower and fuel efficiency.

Fuel Pump Size (gph) = (Horsepower * Fuel Efficiency) / 6

Variables:

- Fuel Pump Size is the required size of the fuel pump in gallons per hour (gph)
- Horsepower is the engine’s power output (HP)
- Fuel Efficiency is the fuel consumption rate in pounds per hour per horsepower (lb/hr per HP)

To calculate the fuel pump size, multiply the engine horsepower by the fuel efficiency and divide by 6 to convert to gallons per hour.

## What is Fuel Pump Size Calculation?

Fuel pump size calculation refers to determining the appropriate size of the fuel pump needed to support the engine’s fuel demands. This involves understanding the engine’s horsepower, fuel type, and fuel efficiency. Proper fuel pump size calculation ensures that the engine receives the correct amount of fuel for optimal performance.
