2days ago I was driving home from work noticed whiny noise from power steering. Got home noticed a little wetness not to bad.next morning on the way to work it was real loud. Today completely mt found bottom hose leaking at metal compression part to hose. The pressure hose that connects to bottom of pump. Where is the best place to buy it? I'm in Austin tx. There is also a hydrolic company that works on on every hydrolic. I would assume they can make them and pressure test them. What do y'all think? I think by now that I purged out all old fluid lol. What fluid did ford use in 2002? What fluid is used in the hydro boost reservoir ?

Id just go to ford for that. It uses tranny fluid. Mercon. It is also what supplies the brake boost, so that fluid is the same. The brake fluid is normal Dot type.

Same thing that just failed on my truck.

I picked up a Dorman branded hose at an auto store. About $40. The hose fails at the swivel.

This is the hose that goes from the power steering pump to the hydro boost unit.

Mobil 1 ATF is a good choice. Takes only about 1 quart. (i think)

Easy to replace, but you have to remove a few things to get access. Like the big tube on the turbo.

What do I torque hose fittings too. Do I use Teflon on the threads?

One more question. How come the hydroboost reservoir did not go mt when power steering went mt?

If you're talking about the swivel fitting on the pump, it takes a Teflon o-ring seal. As far as torque, It should be snugged up without giving yourself a hernia. It you're talking about tapered pipe threads, then you should use some Teflon tape on the threads, taking care not to lap it over the end of the male threads. Those also get snugged up by judgement. A one hand squeeze of two line wrenches should be plenty.

There's just an accumulator on the hydroboost that stores pressure. If you 're referring to the brake master cylinder reservoir, that's a whole different system, not connected with the PS pump and hydroboost, except mechanically.
