'98 ZR2, SAE 30R7 for oil?
So my "coil" of tubing that the power steering pump uses in front of the A/C condenser sprung a leak. In lieu of replacing it, I simply cut off the lines behind the headlight and ran an SAE 30R7 fuel line tube in a loop.
It looks like the pressure and temperature of the cooling oil is well within limits of what the oil flow is, but I want to be sure.
What is the temperature and pressure the power steering pump uses to flow its oil in its front cooling coil?

The temperature and pressure shouldn't concern you as much as the chemical compatibility of running power steering fluid through a "rubber" fuel line. I've been told that power steering fluid will destroy fuel lines from someone whose advice I won't ignore. Better safe than sorry.
I replaced my power steering cooler this spring. I used a Hayden #1009. My original thought was to make one out of steel tubing but I wanted one with fins for better cooling. $20 with a lifetime warranty and it came with tubing and clamps.

Where did you mount it? Any pictures?

I re-used the bracket that the old cooler was welded to. I cut the old metal tubing off so I was left with the vertical bar that bolts to the top and bottom of the core support. I drilled holes in it so the plastic zip tie things would hold the cooler in place. You could mount yours to the front of the A/C condenser like the instructions . My condenser has a leak and I didn't want to mount it on a part that I plan to replace. The shiny aluminum cooler mounted that close to the grille stood out like ***** on a tall dog so I painted it black and reinstalled it. No problems in 4 months and if it ever leaks O'reilly will give me a new one.

Pressure is of no concern as the cooler is in the return line, which has very low pressure. However, as Rusty mentioned, the type of line that you use is a concern. For splicing short distances, rubber is fine, but it must be rated for automatic transmission fluid, not oil or fuel.

I also got the Hayden #1009 from O'Reilly auto parts for $19.99. Hooked it up and used the enclosed tie to cinch it to the bracket after I cut off the metal tubing and buffed them down on the bench grinder. The red circle is b/c I also posted another question about the "plug without a home".
