GFB FX-S Fuel Pressure Regulator - 1/8 NPT Ports

GFB have incorporated a softer, more compliant yet resilient material for the valve seat, which will always positively seal and hold fuel pressure on shut down, designed to give factory-like sealing and reliable startup, as well as superior fuel resistance suitable for Unleaded, Ethanol, Methanol, and Diesel fuels.

• Brand : GFB
• 4x 1/8” NPT body ports which can be used for any combination of fuel inlet/s or pressure gauge/ECU sensor, and 1x 1/8” NPT return port
• Flows up to 750 litres per hour @ 25psi
• 1:1 fuel pressure rise rate
• Double layer/double reinforced diaphragms with a burst strength exceeding 500psi
• Teflon co-polymer seat with spherical stainless valve to retain fuel pressure longer after shut down
• Spring pre-load adjustment screw is o-ring sealed and does not leak vacuum/boost
• Static pressures adjustable from 25psi to 80psi
• Completely serviceable
• Suitable for all fuels

What does this mean? Conventional aftermarket performance Fuel Pressure Regulators typically utilize a metal-to-metal valve and seat which by nature will not positively hold pressure when your engine is shut down, which can make startup more difficult.

We also use a double layer diaphragm, which means we have twice the reinforcing material, and as a result the burst strength exceeds 1000psi!

The multiple inlet/gauge ports also allow 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 you to run a mechanical fuel pressure gauge AND an ECU fuel pressure sensor if you want to.
