Pic #2...shows the distance between the pulley and the tube...and that is with me bending the tube slightly....
Pic #3...is the measurement I get between the pulley and the tube... pulley spins freely....but I'm feeling a little uncomfortable with the clearance and don't want to destroy the tube by bending more... now the AC line looks to be about the same configuration as the factory line with which looks like the correct bends... in Pic #4....

Thoughts.....

Tom, on the high pressure hose, maybe try some type of thread lock. I say that because I have the same fittings on my replacement hose. I torqued it down as far as I felt comfortable doing so. Everything was fine for a few weeks. This Easter Sunday, I lost my power steering and had to get a flat bed home. Today I went out to look everything over and the fitting had backed out enough to let fluid spray out until I was pretty much out of fluid.

I got lucky with a 16mm line wrench that I was able to snake through one of the holes on the pulley to retighten the fitting. Sure beats having to drain coolant to take the whole unit off to tighten one fitting. I got it as tight as I comfortably felt I could without stripping the threads. At the very least keep track of the thread(s) visible once it?s fully torqued down or put a mark on the fitting and on on the pump that line up so if the fitting does move, you can visually verify its backing out.
