Fuel Pressure Regulator EFI Style 35-90psi Blue

The Edelbrock Fuel Pressure Regulator EFI Style 35-90psi in blue is a precision electronic fuel injection regulator designed for modern EFI fuel systems running gasoline, E85, or methanol. This regulator is ideal for both street and performance applications, ensuring stable fuel pressure for optimal engine performance.

Engineered as an in-line regulator, it maintains consistent fuel pressure across a wide operating range, which is critical for fuel atomization and injector response. The regulator features a durable aluminum construction with a blue anodized finish, providing corrosion resistance and longevity in engine environments. Its design includes 10 AN female O-ring inlet and outlet connections, a 6 AN female O-ring return line, and a 1/8-inch NPT gauge port for seamless integration into EFI systems.

This regulator is particularly beneficial for builders and tuners who require dynamic pressure stability during acceleration or load transitions. The 35–90 psi adjustment range is suitable for EFI conversions and performance builds, ensuring that fuel pressure scales with engine demand. With its bypass design, it helps prevent pressure spikes, protecting injectors and fuel rails from potential damage.
