Fuel Line and Fuel Pump Sizing Calculator

Vehicle and fuel details

Fuel tank / vehicle platform Used for pump-housing fitment and related product recommendations, not engine identification.

Fuel system application Engine swaps are sized from the values below while pump recommendations remain based on tank / housing fitment.

Important

This calculator provides a planning estimate, not a guarantee of fuel-system capacity. Pump recommendations use the pressure / flow points entered in the Theme Customiser and interpolate only between published points. Confirm manufacturer data, wiring voltage and fuel pressure under load before relying on the result.
