Radium Fuel Level Diagnostic Indicator

Radium Fuel Level Diagnostic Indicator (20-0508)

The Radium Engineering Fuel Level Diagnostic Indicator is an LED visual reference designed for use with the Radium 20-0461 Fuel Level Switch. When the fuel level switch is triggered, the signal is sent directly to this LED indicator — providing a clear visual alert for low fuel level. While not always practical to monitor while driving, it is particularly useful for diagnosing potential fuelling issues during setup and testing.

Note: Soldering is required for installation.

Installation Notes

• Requires a 2AN ORB (5/16"-24) threaded port for mounting
• If stacking on top of the fuel level switch (as shown), a minimum panel thickness of 0.75" is required
• Soldering is required — all necessary components are included in the kit
