Normally a blown PS hp hose is a hard kill. You go nowhere without a spare unless you have arms of iron and dont mind destroying the pump when it runs dry. To make things worse PS fluid is highly flammable and most blown hoses dump fluid on the exhaust manifold.

Taping, splicing, hose clamping simply dont work on a 1600 psi hydraulic hose. I've seen it tried and I have tried it many times in hopes that it would at least slow the leak or stop it. It has never worked.

If you drive without fluid (it leaked out of the blown hose) you destroy the pump. You cant take the belt off the pump since it also runs the alternator and water pump.

I had a hose pin hole then crack open at last weekend. I was shown a trail fix that allowed me drive 40 miles round trip to get a new hose. I had PS the whole way there and back and only lost a tablespoon or two during the trip.

The FIX
Take a pair of big plier or vice grips and nearly flatten the metal line on the HP hose where it comes out of the pump. The idea is to leave just a tiny, tiny passage in the metal line. This passage is a restriction that creates a huge pressure drop on the steering box side and reduced fluid flow dramatically. Now put a couple wraps of duct tape over the cracked or pin holed part of the hose. Now put as many hose clamps on the hose on top of and on either side of the hole as you can and tighten them down. The pump has internal bypasses that limit its pressure so dont worry about damage to the pump doing this.

How it Works (and a warning)
The reduced pressure due to the restriction will allow the tape and hose clamps to seal the leak. Since you get a lot less fluid volume to the steering box you MUST "steer small". By steer small I mean as little turning of the wheel as possible and as slowly as possible. If you ask to much of the steering box you will use up the available low pressure fluid and suddenly have stiff steering. I only had this happen when in the autozone parking lot.

I think it will also work on a crimped fitting that leaks (very common failure) since the hose clamp will squeeze the hose down onto the internal barbed fitting that is just below the edge of the crimped cap.

In a worst case scenario you can crimp the hard line shut giving you manual steering but still preserving the box.

Be careful with a leaking PS hose. The fluid is highly flammable and any leaks will put fluid on or near the exhaust manifold.
