GFB FX-S Fuel Pressure Regulator | 2002+ Ford Falcon XR6 (8051)

2002+ Ford Falcon XR6 FX-S Fuel Pressure Regulator by GFB

GFBs popular and compact FX-S Fuel Pressure Regulator is now also available as a direct drop-in replacement for common Bosch regulators that clip into the fuel rail.

If you increase the performance of your engine, you need to ensure your fuel system can deliver the goods or youre going to have a bad day! Upgrading the fuel pump is the first step, but doing this alone will usually result in excessive fuel pressure, especially at idle. This is because the factory Bosch regulators typically dont flow enough to support larger fuel pumps, especially with turbo E85 setups that demand high fuel flow rates.

Rather than replacing the entire fuel rail, or using an adaptor with a separate fuel pressure regulator, simply clipping in the FX-S 8051 will allow you to run a much larger pump setup even with the factory rail. And if you need to adjust the fuel pressure, thats no problem unlike the fixed-pressure Bosch regulators, the FX-S can be adjusted from 1.4 bar to 5 bar.

Like all GFB FX regulators, the FX-S 8051 is compatible with pump gas, Ethanol, or Methanol, and also incorporates a soft Teflon valve seat (rather than metal on metal) that will always positively seal and hold fuel pressure on shut down for reliable engine startups.

The double-layer diaphragm has twice the reinforcing material of the single-layer type used in most regulators, and as a result, the burst strength exceeds 500psi! The 1/8 NPT port can be used for a fuel pressure gauge or electronic pressure sensor, or it can simply be plugged in using the port plug provided.

Features

• Direct fit replacement for Bosch clip in regulators (see below for fitment info)
• 1/8 NPT gauge port
• Double layer/double reinforced diaphragms with a burst strength exceeding 500psi
• Teflon co-polymer seat with a stainless valve to retain fuel pressure longer after shut down

• Static pressures adjustable from 1.4-5bar (20-72psi subject to pump flow and factory return line restriction
• Completely serviceable

Benefits

• More than double the flow of the factory regulator, allowing increased pump capacity without having to replace the factory fuel rail
