GFB FX-S Fuel Pressure Regulator – Universal – 1/8" NPT

GFB FX-S Fuel Pressure Regulator – Universal – 1/8" NPT

Application: Universal
Part Type: FX-S Fuel Pressure Regulator – 1/8" NPT

GFB built its reputation on precision engineered EFI hardware, and the FX-S fuel pressure regulator (SKU 8050) continues that standard. Designed as a factory-like replacement with serious upgrade potential, it uses a Teflon co-polymer valve seat instead of the usual metal-to-metal setup, giving more reliable sealing and easier startup after the engine's been switched off.

This listing covers the GFB FX-S 1/8" NPT Fuel Pressure Regulator, a universal fitment unit suited to petrol, ethanol, methanol and diesel fuel systems. Its multiple port layout makes it adaptable to parallel fuel rail setups or deadhead return-less configurations.
