GFB - FX-S Bosch Replacement Fuel Pressure Regulator

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

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 using the port plug provided.
