This item is required when installing a remote adjustable fuel pressure regulator on your BMW. This unit replaces any standard Bosch fuel regulator that fits into the fuel injection fuel rail. This unit seals the regulator location allowing the fuel rail to be flow through. The remote adjustable regulator would be spliced in line between the exit port of the fuel rail, and the return fuel line. C.N.C. machined from billet aluminum. This item will fit most vehicles that use the Bosch fuel rail mounted regulators. Not designed for any late model closed loop fuel systems. Includes aluminum block off and "O" ring.
