The Turbosmart FPR8 Fuel Pressure Regulator is a high-performance, boost-referenced fuel pressure regulator designed for EFI fuel systems requiring precise and stable fuel delivery. Engineered to support fuel systems producing up to 2,000 horsepower, the FPR8 delivers accurate pressure control across a broad range of street, racing, and high-boost applications while maintaining a consistent 1:1 manifold pressure ratio.
Constructed from lightweight billet aluminum with stainless-steel internal components and a military-spec diaphragm, the FPR8 is built for durability in demanding environments. The regulator features-8AN inlet, outlet, and return ports, making it ideal for high-flow fuel systems. Adjustable from 35 to 80 psi (2.4-5.5 bar), it allows tuners to precisely dial in fuel pressure for gasoline, E85, methanol, and diesel-fueled applications.
Its compact design simplifies installation while providing dependable fuel pressure control for naturally aspirated, supercharged, and turbocharged engines. An integrated 1/8-inch NPT gauge port allows convenient pressure monitoring, and the included mounting hardware helps streamline installation in custom fuel systems.
