GFB FX-D fuel pressure regulator features:

• 2x -8AN inlet ports, 2x 1/8” NPT pressure gauge/sensor ports, and 1x -8AN return port
• Flows a massive 1800 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
• Multiple body ports allow for a large variety of setup options

GFB’s Fuel Pressure Regulators are built with the same precision, machining quality, and reliability that is the foundation of all GFB products. The compact size of the GFB FX regulators conceals a large flow capacity, and the multiple ports allow for a variety of fuel system setups including multiple rails and gauge/pressure sensor monitoring.

Internally, like all GFB products you’ll find unique features and small touches that make the difference between a good product, and a great one. For example, we use a double-layer, double-reinforced diaphragm with a burst strength exceeding 1000psi (68BAR)!

Unlike others that use a metal-to-metal valve seat, the FX regulators feature a replaceable soft Teflon valve seat that helps retain fuel pressure longer after the car is shut down for easier re-starting. We even went to the trouble of adding an o-ring sealed spring hat to ensure no boost/vacuum leakage through the spring adjusting screw.

All FX regulators have a 1:1 fuel pressure rise rate and a base pressure range from 28-72psi (2-5BAR).
