Radium Fuel Pressure Test Kit

Radium Fuel Pressure Test Kit

The Radium Engineering Fuel Pressure Test Kit contains everything needed to remote mount a fuel pressure gauge or pressure transducer from any fuel rail or pressure regulator with a 1/8" NPT female port. Ideal for situations where direct mounting to the fuel rail is not possible due to confined space, or where the gauge would not be easily visible in its standard location.

The kit also includes a Schrader valve for pressure testing, bleeding air from the line, fuel sampling, or safely relieving fuel pressure before service. Can be used as a single-use diagnostic tool or left on the vehicle as a permanent installation.

Note: Gauge or transducer not included. Always use PTFE tape or paste on all NPT threads.
