Fuel sender checks on Wranglers
On a TJ or LJ Wrangler, the sending unit sits in the fuel tank, where a float tracks fuel level and sends a signal to the dash gauge. Age, heat and fuel additives can corrode the wiper contacts or crack the float, so a sender that has served for many years may give a gauge reading that stays low or does not move.
Before replacing a sender, check the fuel gauge circuit and the wiring at the connector. A corroded plug or a poor ground can mimic a failed unit. If the gauge has been stuck, a quick voltage check at the connector can show whether the sender or the wiring is the cause.
Fuel system work carries fire risk. Relieve pressure, disconnect the battery, keep the area ventilated and avoid sparks. Replacing the tank seal and lock ring at the same time helps prevent future leaks at the opening.
- Inspect the connector for corrosion
- Test the gauge circuit before replacing
- Keep the battery disconnected during work
- Replace the tank seal when the unit is removed
