Fuel Pressure Gauge Rail or Regulator Mount

(No reviews yet) Write a Review

This is our go-to glycerin filled fuel pressure gauge. Install it on your external fuel pressure regulator or directly to a fuel rail. Reads 0 to 120psi. Very small in size for that compact fit. Uses a 1/8npt male thread fitting to attach to most standard adjustable fuel pressure regulators including the Fuelab options offered here on the site.
