GFB FX-S Bosch Replacement Fuel Pressure Regulator

Purpose-Engineered GFB Performance Hardware

Upgrade or service your performance setup with the GFB FX-S Bosch Replacement Fuel Pressure Regulator, identified by GFB part number 8051. Australian manufacturer Go Fast Bits develops turbocharging, pressure-control and associated performance hardware for enthusiasts who value dependable operation and well-considered engineering. This adjustable fuel-pressure-control component is intended to address a specific function within a properly matched vehicle or performance build.

Application-Specific Engineering

This product is best assessed by the job it performs within the complete system. GFB designed the fuel regulator category around fuel-pressure management for a compatible modified or replacement fuel system, making it relevant to engine builders refining the fuel delivery system. A successful upgrade starts with correct dimensions, interface matching and appropriate installation methods rather than relying on generic claims about horsepower or driving feel.

Its principal functional benefit is fuel-system control rather than an acoustic change. This FX-S version is intended as a Bosch-style rail-mount regulator replacement. It is not interchangeable with the 1/8-inch NPT ported FX-S version; inspect the fuel-rail interface before purchase. Avoid applying specifications from similar-looking GFB products to this exact SKU, especially where connection sizes, spring ratings, fuel-system requirements or mounting points differ.
