Choosing a fuel pressure regulator
Match the regulator to your fuel-system layout, required pressure range, pump flow and fuel type. Compare connection sizes, mounting options and the model-specific vacuum or boost reference requirements. A direct-mount regulator and a multi-port regulator have different installation requirements, so check the instructions for the exact part.
Use our fuel pressure regulator buying guide to plan the setup. If you need help, contact us with your engine, fuel type, pump arrangement and target fuel pressure.
For adjustable EFI systems, read our guide to choosing an adjustable EFI fuel regulator for pressure range, flow capacity and fuel compatibility considerations.
