Key features

  • Fits 15 and 19 gallon gas tanks
  • Sending unit lock nut from Jeep
  • Fitment list covers YJ, TJ and LJ Wrangler models

Lock nut versus lock ring

A sending unit lock nut clamps the unit to the tank opening and holds the seal in place, so its job is similar to a lock ring but the fastening method can differ. On YJ, TJ and LJ Wrangler models, the nut is usually reached through the tank opening, which makes it easy to drop or cross-thread if the unit shifts during removal. Check the nut’s threads and any flat faces before using it, since damaged threads can strip when tightened.

Buyers often confuse lock nuts with lock rings, so compare the shape and fitting method with the part you removed before ordering. Care for the nut is simple: keep the threads clean, avoid overtightening, and replace it if it cracks or bends. Gasoline vapor collects around the tank opening, so keep ignition sources away while the unit is out, and work in a ventilated area.

  • Clean the threads before reinstalling
  • Tighten evenly and avoid overtightening
  • Replace the sending unit gasket at the same time
  • Check for fuel odor after installation

Questions & Answers

Does the Jeep 52005389 fit a 15 or 19 gallon gas tank?

Yes, it fits 15 or 19 gallon gas tanks. Confirm your tank size before installing, since a different capacity may need a different nut.

It covers the 1991–1995 Wrangler YJ, 1997–2006 Wrangler TJ and 2004–2006 Wrangler LJ Unlimited in several trims. Confirm fit for your JK or JL before ordering, as those models need their own check.

What is the Jeep part number and UPC?

Jeep part number 52005389 with UPC 70000432557 identifies this sending unit lock nut. Compare it with the nut currently on your tank before installing, since the nut is different from a lock ring.

Can the old lock nut be reused?

Reuse it only if the threads are clean, the nut turns smoothly and nothing is bent or cracked. Replace it when threads are stripped or the nut no longer holds the sending unit firmly, since a loose unit can shift and leak at the opening.
