Universal EFI Adjustable Bypass Fuel-Pressure Regulator (15–60 PSI) by Holley®

Die-cast aluminum bypass regulator with gauge port and 1:1 boost-reference connection.

This Holley® EFI bypass-style fuel-pressure regulator offers an adjustable 15–60 PSI pressure range for compatible return-style fuel-injection systems. Its die-cast aluminum housing provides 3/8-inch NPT inlet, outlet and return connections, plus a 1/8-inch NPT gauge port and 1/8-inch NPT boost/vacuum-reference port for 1:1 referenced operation. The regulator returns excess fuel to the tank while controlling rail supply pressure. Choose the chrome or black finish specified by the selected vendor part; verify return-line plumbing, mounting location and the injectors’ pressure requirement before installation.

• Adjustable 15–60 PSI EFI fuel pressure • Bypass/return-style fuel-system operation • Die-cast aluminum housing • 3/8-inch NPT supply and return ports • 1/8-inch NPT gauge and boost-reference ports • Chrome or black finish by option
