PS fluid leak: source location(s)?

PS fluid leak: source location(s)?
I have a slow leak which I originally thought was the high pressure hose, but now I'm not sure. Here's a photo from under the passenger side. The R&P boot is completely covered in fluid, but that unit was replaced about 40k miles ago (under ext'd warranty, thankfully). I'm seeing a drop of fluid at the coupling of the high pressure hose (blue box), and the fluid line itself is covered (yellow box). These are higher than the boot.
Thoughts/suggestions? Thanks.

2008 g35.
mine was leaking somewhere as well.
it soaked the alternator and I was worried it would cause it to crap out.
found the return/low pressure line from the reservoir to the pump was leaking. weaping out of the rubber.
had to go to 3 shops to find someone that carried a power steering hose that size. everyone tried to sell me a coolant hose instead.
you might check if it is coming from higher up.

My VQ35HR had a leaking o-ring at banjo bolt on top of the PS pump and was sipping down all over the alternator. The bolt was really tight with copper washers but there is also a o-ring inside there.
2 steps:
1: degrease, degrease, wash, rise and dry.
2: Lift front end, start the engine, lay down and start watching for leaks.

Thank you. I don't see an o-ring on the service manual diagram (see below). Though I think there is one on the pressure sensor.
I was under there as you suggested, and saw a leak coming from the top of the hose. I have a replacement on the way, but now
that you mention it, I suppose it could be the connection at the banjo fitting (though it was dripping down the hose, not onto the
alternator).

I had that leak last year and now that i think about it, the o-ring was inside the pressure sensor and that was the leak for my PS fluid. You should replace that o-ring and check the copper banjo bolt seals, that bolt is TIGHT so be careful not to strip it. Take care of that first as it's the highest point of leak and also, replace the clamps by the PS fluid tank, mine were weak and were leaking also so i've replaced them with screw clamps and no more leaks.
