Overview
The Crown Automotive J5357373 is a sending unit only, made for a 15 gallon fuel tank. It fits the 1969–1983 Jeep CJ5, 1969–1975 CJ6, 1976–1986 CJ7 and 1981–1985 Scrambler, so one part number covers several early CJ models and the Scrambler.
Its resistance readings are 73 OHM empty, 10 OHM full and 23 OHM half, and those values can be compared against the gauge before the unit goes in.

Reading the gauge correctly
A sending unit works with the gauge as a matched pair. The unit changes resistance as the float moves, and the gauge interprets that change as fuel level. A new sender can still read wrong if the gauge or its ground is faulty, so confirm the wiring path before assuming the sender is at fault.
Testing a sender off the vehicle is a practical step. Connect a multimeter across the terminals and move the float arm slowly through its full travel, watching for smooth resistance change without dead spots. Compare the readings with what your gauge expects before fitting. On an older CJ or Scrambler, a bent float arm is a common cause of uneven readings.
- Smooth float travel with no sticking
- Clean ground at the sender and gauge
- Stable voltage at the gauge
- Bench test before installation

Vehicle fitment
It fits the 1969–1983 Jeep CJ5 (Base, Golden Eagle, Laredo, Limited, Renegade), 1969–1975 Jeep CJ6 (Base), 1976–1986 Jeep CJ7 (Base, Golden Eagle, Golden Hawk, Laredo, Limited, Renegade) and 1981–1985 Jeep Scrambler (Base, Laredo, Renegade, SL, SR).
Wrangler and other Jeep models are not covered by this fitment. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Compare the 73, 10 and 23 OHM readings with your gauge’s specification before fitting, since a mismatch gives wrong fuel readings.
What’s included
