Direct-Mount Fuel Pressure Gauges
These compact fuel pressure gauges are typically mounted in a fuel line or directly on the fuel pressure regulator. They are liquid-filled for vibration resistance.
Note: Liquid-filled gauges are filled approximately 90% full of liquid. An air pocket must be left to allow room for the liquid to expand and contract with temperature changes. It is normal for the air pocket to be visible in the face of the gauge. This is not a defect!
