Fuel Pressure Regulator - 30-70 PSI Adj.

The Fuel Pressure Regulator - 30-70 PSI Adjustable by FAST Electronics is an essential fuel system component for street rods, performance builds, and late-model engine swaps where fuel pressure tuning is critical. This regulator is designed to maintain precise fuel pressure, which directly impacts engine efficiency and overall drivability.

Featuring a 30–70 PSI range, this adjustable regulator covers most carbureted and EFI applications without requiring multiple units. Its internal valve design helps maintain steady fuel pressure as pump volume increases with engine RPM, ensuring consistent performance across varying engine loads.

Engine builders and tuners rely on this regulator for naturally aspirated and supercharged engines running OEM or aftermarket fuel pumps. Its compact footprint and lightweight construction make installation straightforward, especially in engine bays with space constraints.
