A big question in the industry is this: how do I choose the correct fuel pump for my needs? Answer: it’s not about the size of the pump; it’s about how much volume the pump can flow. There’s a lot that goes into the decision-making process, even for something as simple as pump flow.

The critical factors that affect fuel pump selection are numerous. The key variables that determine which fuel pump is suitable for a particular engine combination are:

Engine flywheel horsepower.

Fuel Type - including gasoline, ethanol and methanol.

Engine fuel efficiency, commonly referred to as BSFC or Brake Specific Fuel Consumption.

Maximum fuel system pressure and the pumps flow volume at that pressure.

Available voltage at the pump under engine load and the pumps flow volume at that voltage.
