Radium Fuel Pressure Gauge w/8AN ORB Adapter

Radium Fuel Pressure Gauge - with 8AN ORB Adapter

The Radium Engineering Fuel Pressure Gauge is a high-accuracy, silicone-filled gauge suitable for all fuel system applications. The silicone fluid dampens needle vibration for stable, easy-to-read pressure readings under all operating conditions. Features an acrylic lens and reads from 0 to 100 PSI (0 to 6.9 BAR) with ±2% accuracy.
