A fuel pressure gauge is essential for setting an adjustable regulator and serves as a valuable diagnostic tool for the fuel system. This compact mechanical gauge features a rear-facing 1/8" NPT thread, making it ideal for direct installation into a fuel pressure regulator or other engine bay plumbing.

The gauge face is custom-designed with a bold 0–100 PSI scale, positioned away from the bezel to provide a wider viewing angle than standard designs. A secondary BAR scale runs around the perimeter, with 3.5 BAR (~51 PSI) marked at the top center hash. This conveniently corresponds to the correct pressure setting for Nissan VQ vehicles when configuring a return-style system on an ECU calibration based on the stock fuel system. For other calibrations, consult your tuner for the proper fuel pressure setting.
