Compatibility and Mounting

Compatible with Radium fuel level senders and other senders using the required 0–90 ohm output. Electrical compatibility depends on the sender rather than the vehicle make or model. This gauge does not provide a universal conversion for other resistance ranges.

The removable four-pin connector simplifies connection and servicing. Check the mounting location, gauge retention and wiring clearance before installation. Radium offers the separate 20-2585 bracket for mounting a gauge at the perimeter of a compatible Radium fuel cell; that bracket is not included in this gauge listing.

Installation Notes

Follow Radium's wiring instructions for the exact gauge and sender combination. Verify the sender's empty and full readings and correct gauge operation before relying on the fuel indication. The gauge reports the sender signal; it does not correct an incorrectly sized, obstructed or incompatible sender.
