GFB FX-R Race Adjustable Fuel Pressure Regulator - Universal

The GFB FX-R Race Adjustable Fuel Pressure Regulator is rated up to 1500HP!

Built with precision, machining quality and reliability that has been the foundation of GFB's reputation. Whether using Petrol/Gasoline, Ethanol, Methanol or Diesel, GFB have you covered no matter the application.

Perfect for a wide range of fuel system setups beyond the usual inlet/outlet, including parallel fuel rail or returnless “deadhead” systems. The two gauge ports allow to run both a fuel pressure gauge & an ECU fuel pressure sensor if needed.

Unlike other FPR's on the market that use a metal-to-metal valve seat, GFB regulators feature a replaceable soft Teflon valve seat that helps retain fuel pressure longer after the car is shut down for easier re-starting. GFB even went to the trouble of adding an o-ring sealed spring hat to ensure no boost/vacuum leakage through the spring adjusting screw.

Features a unique co-polymer valve seat which holds pressure when the engine is shut down, ensuring an easy startup. Also features a double layer reinforced diaphragm with a burst strength exceeding 1000PSI!

2x AN6 inlet and 1x AN6 outlet female threaded ports as well as 2x 1/8 NPT female threaded ports for a fuel pressure gauge, pressure sensor pick up or nitrous.

Adjustable from 28 to 72PSI, and includes mounting bracket.
