High pressure power steering line leak.
Well, what i thought was a leak from the LP line is in fact from the HP line. Over a period of a couple of days i got the car up ..cleaned..then drove...then inspected....rinse wash repeat a few times. Looks like very tiny leak just prior to the fitting. I cleaned the hose off and got it completely dry, plugged one end and ran some air through it.....sure enough under some pressure a bit of residual fluid came to the surface of the hose. seen below.
also...what is the purpose of the metal "crimped" part on the HP line. I was under the impression the restriction was located elsewhere?
my car is pretty damn clean underneath and even so , this job is a PITA.
the rubber shroud was over the hose PLUS i have an extra home made heat shield protecting the area.

Just take it to any of the truck hydraulic repair businesses in your area. Will cost next to nothing to put newer hoses on with your own fittings. That's what I did 8 years ago and still going strong

There's been several mentions of the purpose of that restrictor in the line. The leading one seems to be it's some method of reducing noise from the hydraulic system.
My experience in having a new hose manufactured, reusing the existing hard lines and deleting that restrictor resulted in a noticeable improvement in low speed turning ease without any negative effects.

What I hear from the "old hands" in the forum is that the restrictor reduced the amount of power assist and offered greater opportunity for steering feedback.
Btw: a good hydraulic shop should be able to crimp hydraulic hose onto metal fittings that will last. I've had good results so far

I had a leak in the HP line a while ago, and had them all rebuilt locally, with no issues. Having seen the potential for fire here, I covered the HP hose with a protective sleeve (Ryco Firesleeve) which will reduce the heat experienced by the hose, and if it does leak, channel the oil down past the exhaust manifold so it doesnt spray everywhere. Have also covered the fuel lines on the other side.

Timely post, priced new replacements at 250 ish.
Anybody have an estimate of pressure requirement?
Steering pump has 75 bar stamped on the tag. That's over 1000 psi, isn't it?
If true, its no wonder we have fires.

79 bucks..its back on the car and up and running. Crimped fittings and 2000psi hydrualic/PS hose. Same place that has done all my other hoses.
RV..it does feel a bit lighter, may be its just me. I have the smaller momo wheel which makes turning a bit harder anyway, but it does feel different.

Which "truck hydraulic repair " do you use?
I have a unit which requires repair but not urgent.
