As long as a fuel pump provides the Flow Rate your engine needs at the pressure your Fuel Injected or Carbureted system requires, it will work just fine. It is just a matter of deciding which one works best for your installation.
How do I know what size fuel pump I need?
To determine the fuel pump size for a naturally aspirated engine, take the projected horsepower and multiply it by 0.38 to determine liters per hour. If you want to convert that number to gallons, divide the answer by 3.785.
Is a bigger fuel pump better?
An upgraded fuel pump may move so much fuel, the factory regulator cannot bleed off the pressure fast enough. This leads to higher than desired fuel pressures which means the injectors are spraying more fuel than intended. The consequence is an overly rich air to fuel ratio and a poorly running engine.
