FPR-800 Adjustable Fuel Pressure Regulator

An upgraded fuel pressure regulator (FPR) is often necessary when upgrading fuel injectors and the in-tank fuel pump. The Turbosmart FPR-800 is a motorsport-proven EFI fuel pressure regulator capable of supporting fuel systems up to 800 HP. It features a 1:1 manifold pressure ratio with no load losses, 30–90 PSI base pressure adjustment, a premium MILSPEC diaphragm, and stainless steel valve and seat suitable for any fuel type including E85. The non-directional bias means it regulates the same no matter where the fuel enters.
