Power Steering High Pressure Hose

I have a 1993 ZJ V8. A few months ago I replaced the lower steering box seals where the Pitmin Arm connects (thanks to this board for all the help!). Now I seem to have another Power steering leak. it looks like it coming from the high pressure hose. It seems to be leaking out of the hose itself where it bends and just brushes the top of the steering box. It looks very rusted, so I am thinking its rusted out. I can't seem to get the hose removed from either the steering box or from the reservoir. Is there a trick to this? I have just been been using an open ended wrench. But there is not much room in there. Do I need a special tool? I also have not ordered the new hose yet, but but I am thinking about replacing both the high and the return lines all at once. Should I grab the hoses from Autozone or do I need OEM parts? Any help would be appreciated. Thanks.

If the line fitting is to tight you will need a crow's foot or a flare nut wrench to remove it to mitigate the changes of rounding off the line nut.

You whould probably do both hoses while your there.

A good autoparts store should have the pressure line, hose for the return, and probably the flare-nut wrench.

what he said ^^^, and to add, if you already have the new hoses, you can chop them off at the fitting, and use a socket, but a set of line wrenches are good to have sitting in the tool box anyways.

an auto parts store ones should be fine, if i don't buy from the dealership i prefer napa though, i think they have better parts than autozone...

I ordered both the high pressure and the return hoses tonight from Autozone. I also picked up a Flare nut wrench and some more power steering fluid. I hope to give this a try this weekend.

Thanks for the help guys. It was easier than I thought. It did take me a while though, about 2.5 hours. I had to cut the old hoses so I could get a socket on the nuts. 300k on the jeep, there was alot of rust. But I got them off. One dumb thing I didn't realize was on the high pressure hose where it attached to the reservoir I didn't at first realize that I could use the top nut, and I couldn't understand how the shop manual just says "remove hose" I was thinking how could they get a wrench in there. Hehehe...oh well. That's what took so long just trying to figure out if I need to take more stuff out. But I got them changed and no leaks. I appreciate the guidance. One of the reason I picked up the ZJ was to learn how to fix things on cars/trucks. So far it working out great.

power steering pressure hose

I'm looking to replace my PSPH does this require bleeding the system? and if so how do I go about doing it, Im looking to do it myself instead of having my mechanic do it since it looks easy enough for me to do.
