Product Description

The Radium Engineering 20-0386 fuel pressure gauge is a precision instrument designed for universal use with 8AN ORB fuel system ports. The included 90° adapter ensures tight clearances and optimal install orientation. The silicone-damped needle provides accurate readings from 0-100 psi, ideal for tuning and monitoring fuel system health.

Built with a durable stainless steel case and clear acrylic lens, this gauge is designed for both form and function. It's not CARB compliant, so it should not be used in California-registered vehicles. Partial to high-performance builds, the 20-0386 is ideal for fuel-regulated setups, surge tanks, and other aftermarket fuel applications requiring reliable pressure monitoring.
