I'll share my experiences with this mod.

I did this mod on both my 98 MarkVIII, and my 90 SC. The MarkVIII had a much shorter hose due to the placement of the power steering pump, and it worked great at first, but periodically it would loosen up and start leaking, and I could never figure out why.

My SC had a power steering leak from the day I got it. I was a little hesitant to do this mod due to my previous experience with the Lincoln, but after replacing the line with the stock aftermarket, the fittings on the rack, the return line, blowing out the aftermarket pressure line, and deleting the power steering cooler cause that was leaking, I went with this. After the install, everything was great for about 2 weeks, then it started leaking again. I tightened the line up again, and basically every 2 weeks it would loosen up and start leaking again, and then eventually the braided stainless line itself blew out. What I found was happening was that once the line is tightened to the adapter fittings, there is no way for it to swivel, and the vibration and twisting of the motor would actually twist the line and loosen the adapter fitting out of the rack, causing a leak. I was so frustrated with this leak that I was to the point of converting the car to manual steering, but before I did, I decided to take this whole assembly to a local hose shop and get their input. They made up a regular rubber hose for me to replace the braided stainless one, and gave me some steel adapter fittings that seal with rubber O-rings instead of the teflon washer. Also, the fittings on the new line still allow it to swivel even when it is tightened up on the fitting. Total cost for the line and 2 fittings was $34, it installed the same as the braided stainless line, and now I finally have no power steering leak. The Lincoln is currently off the road, but before it goes back on the road, it will be getting the braided stainless line removed and replaced with another rubber line just like the one I got for the SC.

Woah I knew you were having issues with the SCs power steering but damn! I'm surprised to hear you blew out the braided hose since the high pressure rated ones are used for brake hoses as well. I here you on the swivel, it seems to only be there to allow it to face one direction while you tighten in another, once it's tight it's stuck.

I bet you're right about the movement of the motor and the vibration being a big contributing cause, especially on the SC since the V6 is inherently rougher. My experience was that the adapter fitting itself was loosening up from the pump with the hose fitting still fully seated, granted my double nylon washer/spacer treatment didn't exactly help but what happened with mine was the sway bar would slightly nudge the hose and twist the 45* fitting lefty/loosey occasionally - had I known the SC/Addco sway bars were different at the time I probably would have actually used a 90* at the pump and the 45* on the rack so the line would go OVER the bar rather than under - The rack side always stayed in place though but then again I left the factory elbow in place with an adapter fitting on it, and I think the factory elbow actually does use an O-Ring to the rack rather than the teflon washer as well, so it makes sense that's what the shop set up for you.

My MarkVIII always loosened at the pump side, and the SC always loosened at the rack side, and yes just like you, the adapter fitting loosened up, but the AN side to the line stayed tight. I also have the factory fittings in the rack with the adapter screwed into that. The braided line blowing, I don't know if it was a production flaw, or if it was rubbing on something while driving, or what, but it popped a hole right in the side! I still have it in the garage, so I'll snap a pic of it when I get home.

Yeah pics would be great, my bet is it probably rubbed the sway bar, mine was always a bit close for comfort so I slipped on some convoluted tubing over the braid to help protect it. Now I kinda wish I would have used thread locker on the adapter to pump threads.

Here's the line...


Here's a close-up of where it blew out. No signs of rubbing that I can see


And here is the new fitting that I got that seals with an O-ring

Yeah that doesn't look like a rub through to me either, almost looks like it was twisted.

Do you know who makes those fittings? those look much more stout than my Russels(are they steel?). on the 4.6 pump it looks like you'll still have to cut it down a bit for the threads to clear the pump orifice.

Yes they are steel, and while I don't know who makes them, I can easily get more if you want them. I actually have a 4.6 power steering pump in the garage, so I can check to see if it would need to be cut down.

Well hopefully the ones I just installed hold up, but if I need to pull them off later I'll keep it in mind. Right now I'm sick to death of this unexpected little project, I just spent the last two hours redoing the low pressure lines, ugh

Well I just found out something irritating, after filling the system and bleeding, the leak I had always been under the impression was coming from the old mismatched adapter fittings, may in reality have been coming from the pump shaft seal upon closer inspection. I thought it was odd that there was already a drip coming from the pressure line since I didn't even start the engine yet, and low and behold a trail of PS fluid behind the pulley, a trail that instantly comes back after wiping it down :mad:


So about that manual steering... :D

For those of us that have a leaky pump elbow fitting, but don't want to drop the rack to install the other end of this mod:

How about cutting the line before the power steering pump elbow and somehow adapting the line to connect to only the pump side of this mod?

I don't know much about adapting high pressure lines to work without leaking. Could someone more knowledgeable show how this could be done?

So, I'm thinking about doing this on my 93 LX with the 5.0 (not 5.0 anymore but anyway). It seems like the adapter fittings from the 94-95 Mustang would work in my case. They use the same pump and I can't imagine that the fittings on the rack would be that different. What is the contraption that sticks out of the side of the pump? It also appears to be have an electrical connection to the pump and that contraption and I don't remember what that is for anymore either.

Anyone care to enlighten me?

Ok, so this is just to shorten the line? What does this actually improve and is this worth it? It looks like a fun project, and it looks efficient, but if it only works for a short period of time then I might need to consider other future options. What all does this benefit and has it caused any other device damage?

It's shorter and all in all it's as much or cheaper than the stock replacement. Madmikey is the only one I know with a line failure like that, I had issues with the fittings due to using the wrong adapters but that seems to be solved now. There's no device damage, just cut down the threads on the pump adapter so the EVO orifice remains exposed within the pump and all is well.

So, what all are the benefits, other then saving money in the future?

The benefit is simply that it's shorter. A possible side benefit is that it keeps potential leaks away from the strut rod bushings, which the stock lines run directly over and if leaking onto them can accelerate their deterioration.

I personally like it simply because I'm using universal parts that are easily replaced and am not at the mercy to Ford or the ever crappier aftermarket for OE replacements. And my K member is super clean! :)
