Description
The Turbosmart FPR8 Fuel Pressure Regulator is a high-flow, performance-focused regulator designed for EFI fuel systems using -8AN / 8AN fuel plumbing.
Engineered to deliver consistent fuel pressure control and rapid response, the FPR8 uses a true 1:1 fuel-to-manifold pressure ratio, helping maintain stable differential fuel pressure under changing boost and load conditions.
The regulator features a stainless-steel valve seat, Milspec diaphragm and Turbosmart’s locking collar adjustment system for accurate and secure base fuel pressure setting. With -8AN inlet, outlet and return ports, plus a 1/8″ NPT gauge or pressure sensor port, the FPR8 is suited to serious street, motorsport and high-performance fuel system applications.
The standard FPR8 offers an adjustable base pressure range of approximately 35–80 psi and is suitable for a broad range of fuels, including petrol, E85, methanol, race fuel and aggressive leaded fuels.
With excellent flow and bypass capacity, the FPR8 is suitable for fuel systems supporting applications up to approximately 2000HP, subject to fuel type, pump capacity, operating pressure and overall fuel system configuration.
