Changing Power Steering Pressure Hose?
Hey everyone. n00b here. I have a 2001 F150 SC Lariat w/110,000 mi.. Had it since new. Its getting on in years and starting to need some TLC now and again. That's okay because the truck was trouble free for the first 105000. I've checked out a few sites and this one seems to be the best. Thought I'd join in.
Anyway, I wave a leak coming from the Power Steering pressure hose. Any tips for changing it? I got the new hose but standard wrenches aren't gonna cut it. Do I have to pull the PS Pump pulley?

Well, looks like the leak is actually coming from the PS Pump itself from the main shaft seal. It was just dripping down the pump from behind the pulley onto the pressure hose fitting. Looks like I have to replace the pump.

Hi and welcome to the forum 
I've replaced quite a few PS pumps on these for the same leak you're describing.
It's a bit of a pain to do but it could be worse. I use a really long (30" or so) extension with a 10mm swivel socket to remove the bolts that hold the pump to the engine.
If you can break the pressure line loose from the pump before you remove it that's easier. The pressure line has an 18mm nut on it. You may need a flare nut wrench for it.
Let us know how it goes for you.

I saw that I need the long extension and swivel before I walked away from it yesterday. It's pretty tight to get a wrench on the pressure line at the PS Pump because of the pulley, but can do it fairly easily from the steering gear. I'll probably just detach it from there and pull it that way. Worst case I can cut the line. It figures it's 18mm at the pump. The new line is 11/16 at the pump, 9/16 at the steering gear. I went out and bought some inexpensive flare nut wrenches yesterday morning, both metric (knowing the existing line would be metric) and standard and thought I would be covered, but 17mm is the largest. Oh well.
I have to go find a pump. Everyone so far says they have to order one. I'll live with the leak for a few more days.
I'll check back in after I've changed it out.

I found a pump for $45 on Saturday and changed it out last night. All in all, not to tough a job. A couple of things to note:
1) You need the right tools to pull and re-install the pully from the old to new pump. I happened to find one at an auto parts store that said it was designed for Fords. Turns out it looks identical to the one called out in the Ford Shop Manual. Put the pump in a vise and it's easy. The pump itself came with a bolt, washer, and nut to use to install the pulley, but I used the tool that I bought.
2) I could only detach the pressure line from the stearing gear so I pulled the pump and pressure line as one.
3) I pulled the #30 fuse to disable the vehicle from starting. After everything was assembled and the reservoir filled, I cranked the engine while turning the steering wheel back and forth from stop to stop. This primed the pump and got any air out of the system. Read that on my Ford Shop Manual CD.
No more leak!!
