The GFB FX-S (part 8051) is a direct-fit replacement fuel pressure regulator for factory Bosch clip-in style regulators, offering more than double the flow of the stock unit, adjustable static pressure from 1.4-5 bar, a 1/8" NPT gauge port, and double-layer diaphragms rated above 500psi burst strength. It is compatible with gasoline, ethanol, and methanol fuels, making it suited to custom EFI fuel system builds.

Fitment: Universal — designed as a rail-mount Bosch regulator replacement for custom EFI and aftermarket fuel system applications rather than a single specific vehicle.
