The GFB Fuel Pressure Gauge is suitable for Petrol/Gasoline, Ethanol, Methanol or Diesel applications and is a perfect match with GFB fuel pressure regulators.
Features an acrylic lens with a silicone filled dial that reads from 0 to 120PSI (0 to 8.27BAR) with +/- 2% accuracy. Silicone fluid prevents the needle from vibrating for easy pressure readings. The internal bubble is normal.
40mm / 1 1.5-inch. 1/8 NPT fitting and is very simple to install.
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).
