Preset to 58PSI (4BAR), -6AN Bulkhead and 3/8" Barb

The Aeroflow Performance In-tank fuel pressure EFI regulator is designed for use with a modern returnless fuel system. This returnless system has a fuel pressure regulator inside the fuel tank. This eliminates the need for a fuel return line from the fuel injector rail on the engine to reroute excess fuel back to the fuel tank. This In-tank fuel pressure regulator is present to a pressure of 58PSI (4BAR) and the remaining will be dumped directly back into the tank. It features a -6AN bulkhead on one side and a 3/8" (9.5mm) barb on the other side.
