Remote steering pump fluid reservoir for stock pump

[mountainjazz]

Has anyone done a mod consisting of replacing a stock power steering fluid reservoir with a remote one (aluminum cylinder), keeping the stock pump? The reservoir on my 99 Classic 4.0I XJ is leaking and I can get a remote canister from a friend's swap. I don't want to replace the pump which is working fine. Thanks in advance

Keep in mind that the pump is not positive displacement. That means it will not draw fluid into it, it has to be gravity fed. I looked into this when I put in the SuperCharger and was not able to locate a suitably high enough place to mount the reservoir. I spoke with the folks at KRC and AGR and both agreed. The bottom of the tank needs to be above the inlet to the pump or it will starve and self destruct.

What I finally decided was that it could not be easily done. A horizontal tank mounted up by the radiator would work except for when going down something steep. Then the level would drop to the point of starvation. Mounting on the firewall looked good until I took measurements and calculated the angle. Starvation again.

I am hopeful that someone her has been successful and will perhaps share a photo of the install. It is something I still would like to do as it should reduce the fluid temps a tad.

You'll have to get a fitting installed on your stock pump for the hose to the reservoir. Get another stock reservoir, they're cheap.

The 4 cylinders use a pump that ( I think) would fit our brackets and uses a remote reservoir. The tank mounts on the core support.

It seems to me you could use an accumulator (like a remote reservoir for a shock) to keep the fluid pressurized going to the pump and also absorb the extra pressure as the fluid heats up during use. It would have to be bled thoroughly though. You end up with a closed, pressurized system that should never be able to starve the pump.

Here is the thing about just replacing the reservoir. You can't. Last year I looked everywhere (inclusing the dreaded dealer) and found that if I wanted just the reservoir, I would have to hit the JY.

If anyone has found a source, please post.

YJ's used a remote res, on what looked to be the same pump.

Yep, you can. Crown automotive sells the resevoir. They are listed for only up to I think a 96 year (I can't remember exactly what year), then they only list a pump and reservoir together but I know for a fact that just the reservoir will still fit on a '99 pump.

ZJ reservoirs (from the 5.2 or the 5.9) fit also. I am running one on my Heep. Needed the side mounted return to clear the gear case of the Supercharger.

What about mounting the ps pump down where the alternator is and relocating the alternator up top? Now it is easy to mount a reservoir above the pump and the alternator won't die in every mud hole.

That would be a good solution but would be a lot of work.

I use a YJ pump and remote reservoir with a late model manifold. I had to drill out two of the three threaded holes to use the long bolts that go thru the pump to the manifold. The third bolt was left short and attaches to the bracket. I also had to swap pulleys to keep proper belt alignment.

^^Could you post photos of the installation? I would be very interest in where you put the reservoir.

Thanks!

X2 I would like to see how that was done too.

@ o-gauge & jeeperjohn, it's not an XJ but a 4.0 swapped into a Scout. I could post pics but it wouldn't help with how to shoehorn the the reservoir into an XJ (and it might not be well received).
