100psi Fuel Pressure Gauge 1/8 NPT Male
An accurate gauge makes it easy to set the pressure on your regulator. This 1.5 inch diameter pressure gauge can be mounted in the engine compartment to monitor the operation of the fuel pump (and regulator, if used). If you are using one of the Holley regulators and are only using one of the outlet ports, the second port can be used for this gauge using a reducing bushing (Part No. 3257-06-02). The gauge can also be mounted in-line using an adapter (Part No. 1069-Size). Face styles may vary.
Note: Liquid-filled gauges are partially filled with liquid, and an air space is provided for expansion and contraction. A visible air bubble is normal.
