Fuel Pressure Gauge
There are two main type of fuel pressure gauges.
1. Dry gauges: mainly used for industrial machines including air compressors. Ideal for environments where mechanical vibrations is not a concern and where there is little to no moisture.
2. Liquid filled gauges: Can absorb vibration and pressure spikes which will reduce the possibility of poor performance or failure. They also keep dirt and humidity out, preventing condensation and reducing visibility problems in high humidity situations.
