Overview
The Crown Automotive J5363490 is a fuel sending unit for 1981–1985 Jeep J10 and J20 trucks, 1981–1985 Jeep Wagoneer (SJ) and 1984–1985 Jeep Grand Wagoneer (SJ). It is a sending unit only, so a fuel pump is a separate purchase.
The sender reads fuel level from the tank and sends it to the gauge. It is for owners of 1980s J-series trucks and Wagoneers who need a replacement sender for the listed trims.

Pump and sender pairing
On J-series trucks and Wagoneers, the sending unit and fuel pump are separate parts that share the tank. A sender replacement does not change the pump, but a worn pump can make a new sender look faulty when the fuel pressure drops. If the engine stumbles or the pump is noisy, test pressure before assuming the sender is the cause.
Pick a sender that matches the tank and the gauge, then plan the pump question separately. Old pump strainers can clog with rust and debris, which can cause starvation under load. When the tank is open, check the pickup screen and the condition of the pump connector. Keep sparks and open flames away from the work, and disconnect the battery before loosening any fuel line.
- Test fuel pressure if the engine stumbles
- Inspect the pump strainer
- Check the pump connector
- Replace pump and sender separately when worn
