GFB FX-S Bosch Replacement Fuel Pressure Regulator
GFB has taken its popular and compact FX-S regulator and adapted it as a direct fit replacement for the common Bosch clip-in fuel pressure regulator found across a wide range of turbocharged platforms. If you're upgrading your fuel pump, the factory Bosch unit often can't flow enough to keep pressure in check, especially on high demand E85 setups. The FX-S solves this without needing a new fuel rail or an external adaptor plate.
This listing covers the GFB FX-S 8051, sold as a direct drop-in replacement for OEM Bosch clip-in regulators. It bolts straight into the factory fuel rail location, so there's no cutting, adapting, or rerouting of fuel lines required.
Note: Static fuel pressure is adjustable from 1.4 to 5 bar (20 to 72 psi), though actual achievable pressure will depend on your fuel pump's flow rate and the factory return line's restriction.
Specifications
- Direct fit replacement for Bosch clip-in regulators
- 1/8 inch NPT gauge port with plug supplied
- Flow rate over double the factory regulator, supporting larger fuel pumps on the stock rail
- Compatible with petrol, ethanol, and methanol
- Double layer, double reinforced diaphragm rated over 1000 psi burst strength
- Teflon co-polymer seat with stainless valve for better pressure retention after shut down
- O-ring sealed spring pre-load adjuster, no vacuum or boost leaks
- Adjustable static pressure from 1.4 to 5 bar (20 to 72 psi)
- Fully serviceable design
OEM part numbers and fitment notes for compatible Bosch regulator applications are provided in the tabs above. Please confirm your vehicle's original regulator matches the Bosch clip-in style before ordering.
