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.

All GFB FX Regulators Feature:

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).
