Radium Engineering Fuel Pressure Gauge with 90° Adapter Universal 0-100 PSI (0-6.9 BAR)

Radium Fuel Pressure Gauge With 90 Deg Adapter

Radium Engineering builds this fuel pressure gauge for motorsport and high performance street applications where accurate, readable fuel pressure data matters. Silicone-filled internals dampen needle vibration for steady, easy-to-read values even under hard driving conditions, and the stainless steel housing is built to handle the heat and vibration of a real performance fuel system.

This listing covers the Radium Engineering 20-0407 fuel pressure gauge with 90-degree adapter. Universal fitment suits naturally aspirated, supercharged, and turbocharged fuel systems across a wide range of vehicles and applications.

Important: Do not exceed 100 PSI (6.9 bar) — overpressurising will permanently misalign the needle calibration. Always use PTFE thread sealant paste on NPT threads when installing. A small internal silicone bubble is normal and does not affect gauge operation.
