A fuel pressure gauge is necessary for setting an adjustable fuel pressure regulator and also makes for a useful fuel system diagnostics tool.
This compact mechanical gauge, with a rear-facing 1/8 NPT thread, is ideal for installation directly in the fuel pressure regulator or other plumbing in the engine compartment.
Our custom designed face for this gauge features a prominent 0-100 PSI scale that was intentionally placed away from the bezel to widen the viewing angle compared to other faces available on these gauges. There is a discrete secondary BAR scale around the outside. 3.5 BAR (~51 PSI) is indicated on the straight upward hash mark, which is conveniently the pressure setting to be used on Nissan VQ vehicles when configuring a new return system install for use with an ECU calibration built on the stock fuel system. For any other calibrations, consult your tuner for your proper fuel pressure setting.
