4.0L power steering pump reservoir availability?

Does anyone know to get a ZJ 4.0L power steering pump reservoir? It is different from XJ/TJ with the return line on the side instead of the back. I have looked around and it seems all I can get is a modified version that comes with remanufactured pumps.

You may have to try the jy and I couldn't find one either without the the nipple on the back. Also heard this is too close to the exhaust on some models being on the back. An OE jy one will give you a thicker plastic reservoir anyhow rather than the newer thin asian ones.

Local junkyards only have V8 wrecks at the moment. I might just have to plastic weld the one I have or go to a remote reservoir.

Dorman carries them, but the way they look you might as well get a milk carton and a straw. I wonder if the dealer still has them?

Is the Dorman 603-902 the one you were talking about coralman? That's the one I bought a few months ago and it matched the one I had on there but my ZJ came with a reman pump when I bought it. Sounds like the OP doesn't like the location of the return nipple. The Dorman one I got wasn't flimsy and it matched what I had.

Are you sure that the reservoir is the source of the leak? I had a persistent leak that I ended up messing around with reservoir O-rings and the reservoir for a while. Turned out the back of the pump was leaking. I fixed it by switching to the later model pump when I swapped in my 99+ intake.

Can you see where you're reservoir is cracked/leaking? I know I had the o-ring leaking problems, as Josh mentioned below, and even might have had a hair-line crack in the pump port where the plastic reservoir connects. Cleaned all the brake fluid off, smeared black RTV on where it connects, and hasn't leaked since.

I looked up that Dorman reservoir Josh as can be seen below.

When I was doing a search last night it directed me right back to this forum where one guy said this nipple on the back is way too close to the exhaust. He said the heat caused the connection to break loose spraying power steering fluid everywhere. Sounds like he just didn't have it connected correctly and do you see where this nipple or hose is near the exhaust manifold on yours?

Where the OE reservoir had nice clean seams, the dorman I got at oreily's looked like it had been put together with a hot glue gun,lol. The adhesive was gooped all along the seams. I had already went through the leaking oring thing and got tired of making trips to the part store. I passed on the reservoir, took the cardone pump back, and got a OE pump. No probs, 2 years so far.

Yep, that's the reservoir I bought and it matched the one I had on my pump already. The glue joints weren't as neat and the pads for the spring clips were a little thicker. I know my old pump was reman but the reservoir looked stock. I put my old reservoir on the later model pump when I swapped intakes. That nipple has got to be like 8 inches from the header. I can't imagine heat being an issue.

The current XJ pump and reservoir in my MJ is fine and not leaking. I need the ZJ specific reservoir since the return line nipple on the back side of the XJ reservoir interferes with the supercharger I am installing. My local LKQ junk yard was being lazy and had just not updated their site for a few weeks. There were two unlisted six cylinders there that were in quite horrible wrecks. One with a XJ reservoir and hammer smashed fuel rail. The second with a ZJ reservoir and a perfect fuel rail. Two for two on parts from the same ZJ. Thanks for the help!
