Power steering fluid leak
My power steering fluid keeps seeping out where the hoses attach to the rack and eventually draining the reservoir (I'm not sure if that's technically "the rack", but he leak is at the lower end of the supply hose rather than the upper/reservoir end). The hoses are really stiff and you'll notice in the pic I have them pretty twisted. Are the hoses untwisting and thus slightly unthreading themselves and creating their own leak? Tyler

what style fitting at the rack? Double flare or oring seal? If the connections are tight they should not leak. Nick in a sealing seat or cut oring are possibilities depending on connection design.

It's a flare fitting. I've tightened it as tight at possible I think.

Leak
I have the same problem with mine, my hoses are custom to fit the CV steering pump and MII rack. Its not enought to drain the resevoir often, but annoying. Its on my to do list, after gauges.

If you are still having problems you can buy fluorescent dye at NAPA that will help show the source under a black light which are sold at many novelty stores.

Are you using a low pressure pump meant for a R&P? R&P use a much lower operating pressure. Flare fittings are only meant to be tightened once or twice, if reused several times or overtightened they can leak. Also the hoses should never be installed twisted, the ends are designed to absorb flex but the hose will not tolerate twisting for very long, especially after the fluid gets heated up. Install the hoses in as relaxed a routing as possible.

I'll double check but I'm pretty sure the splines of the rack are fully inserted into the universal joint and are flush with the inner edge. Thanks!! Tyler

If it's leaking without any pressure on it, you have a real problem. With everything new it should be real easy to spot where the leak is coming from. Isolate the source of the leak then replace whatever is connected at that point: hose, seal seat, etc. Do not overtighten flare fittings, you are just pressing the soft flare against the seat. It should NEVER be tightened enough that the tube flare turns with the nut.
