Adapt CJ Fuel Gauge to Wrangler Sending Unit


Recommended Posts

For all you electronic handy techs, here is a quite simple adapter allowing the factory CJ Fuel Gauge to use a Wrangler Sending Unit.

Fuel tank needs to be well grounded for gauge accuracy.

I added enough tank to frame strapping to reach a low level of 0.003V between the tank and frame when the fuel pump is running.

See attached schematic.
