The power steering system in my Prelude has been leaking: lots. 20year old Hondas are doing this now.
There's a cooler. It's corroded. I replaced it with a weird home-made thing from a scrap car.
Leaks didn't go away, but they're on the return line and not under too much pressure, so I bypassed bits of the old corroded pipes with new reinforced hose.

Here's the doh! moment:-

It turns out that the hose I was using is fuel line spec ... and it can't deal with the aggressive chemistry you find in Honda-approved PS fluid. I'm now talking to hydraulics specialists.

It's cautionary tale.

if its the return hose, just order a small roll of hydraulic hose on ebay. its not some special honda hose required.

possibly as cheap as $5 USD per foot shipped. look for ones with actual chemical certificates and ratings

Spot on.

I'm now using hydraulic hose with a new stainless steel loop for the cooler.
I really need this to work - I want to take it to Germany next week and then on to Switzerland and Austria (lots of steering inputs needed!)

If it comes down to it check out the Tron stezzy PS discussion HiiProfile and I had in the DIY section.

Might be worth looking into.
Thaks for that. A good read.

I know of a couple of Preludes over here with power to manual steering conversions. The consensus seems to be that it's worth doing for track days but that our shitty roads make it better to have some sort of power assistance / bump-steer smoothing in a daily driver.

I just got it wrong. The car was a dream to drive before, so it's up to me to get it right.

Next job: make the rear wheel steering more reliable. At nearly 160,000 miles, it's lasted longer than many of its brothers.
