2003 3.0L Power Steering Hose Leak

Happy New Year everyone! my PS line that goes from the reservoir to the cooler (low pressure) as it only has the expandable clamps is leaking, I tried to do a search for the part number and I come up with this: Part Number: F87Z3A713AA However, it says discontinued and no longer available. Has anyone else tried to replace this hose and ran into the same issue? Since it does not appear to be a special type of hose (no particular bends or shape) can this be replaced with some kind of oil resistant hose? Any suggestions on what kind and what size? I think this may be purchased by the foot as a power steering hose but would like to confirm Thanks

Ok, I dug a bit deeper and need some additional information please. Can someone with a 3.0l 2003 (is the YM) I have check the upper high pressure power steering hose going from the upper portion of the PS pump to the steering rack see if theirs moves (rotates) easily but the nut is tight? Mine does and I am not sure if this may be an additional source of my leak.
thanks in advance for checking

My nut is tight, but the actual line is quite loose.
I can even move it from side to side.

If yours is leaking there, the O-ring(s) on that fitting need replacing.

I didn't check the lower connection though.
It's cold and raining here and I'm not crawling around underneath the truck.

Outside temp is only 3 degrees above freezing today... Blah !

Hey Thanks Jeff R1, much appreciated. The bottom one is dry no issues there, i appreciate you checking despite the miserable weather conditions you're in. Yes mine does the same thing but just sitting for a couple of days after I wiped it clean and used brake cleaner to get the area nice and clean and this afternoon, it's seeping again. So you are saying that all I need to do is replace the O ring, not the entire hose? I guess the O ring has to be one that is specifically made for PS fluid as rubber and oil and fluids don't last too long. Any leads on where to get one?

There are at least 2 O-rings involved, the one that seals the metal body to the plastic reservoir and the high pressure one on the line.

The low pressure one is more likely causing the leak on yours.
You have to remove the line and then unscrew the big nut in the metal housing.

When I rebuilt my pump, the kit contained the wrong size.
I went to a hydraulic shop where they rebuild things and it is supposed to be a metric size.
The imperial sizes were just a bit over or under.
Don't ask my why Ford decided to use one metric size O-ring on that spot.

When you take the big not off, you will have to use a turkey baster to remove some of the fluid in the reservoir of course.

I think one of them is a 14mm and maybe an 18, I know I had to go out and buy the proper wrenches.

Also, if the high pressure line was leaking, there would be oil all over from here to kingdom-come !

And about O-rings, they are all made to with stand fuel and oil, that's the whole point of them.
At any rate, if you get them from an auto parts store, you should be OK, I wouldn't get them form a hardware or plumbing store.
They're supposed to be made from neoprene _ a synthetic rubber.

Good to know thanks, yes it is making a mess as I thought it was the low pressure hose but I think it has been leaking (as you said) all over and made it look like the low pressure one is the one leaking, until I looked up and saw the moisture coming from around the metal line that swivels not the nut so........being on top and the low pressure line is below it it gets what is dripping from above.
