Sender replacement on CJ models
On CJ models the sending unit sits in the top of the fuel tank, where a float arm moves a wiper across a resistor to change the gauge reading. Over time the wiper contacts wear, the float can develop a leak, or the resistor strip can corrode. A gauge that reads erratically or stays on one spot often points to the sender.
Because the O-ring seals the tank opening, a replacement sender should come with a fresh seal. Clean the sealing face and inspect the lock ring threads before tightening. Many owners replace the sender while the tank is low, since working on a near-empty tank reduces spill risk.
Fuel system work carries fire risk, so disconnect the battery, keep sparks and open flames away and work outdoors or in a ventilated space. Check the gauge after fitting and look for leaks at the seal before driving far.
- Clean the sealing face before fitting
- Inspect the float arm for bends
- Check the gauge on a test drive
- Replace a hardened O-ring with the sender
