Supposedly the Some Kia models used the same pump.
Kia part number 510303E100.
You might also search the wrecking yards and check Davey’s Jeep.
Additionally, check through the locker pump posts on this forum as I recall there is a company that was doing rebuild exchange on them.
Welcome to ROF. A few months ago, there was a company that refurbished lockers. I don’t remember anyone from the forum actually giving feedback from their experience with them. I would probably mention them by name if I had. I had ARB‘s on my ‘84 CJ and plan to go that route with any of my own locker failures of any type.
