I wonder if that loop in the power steering line is causing problems? From what I remember, the line needs to be as straight and short as possible.
Edit: I guess I should read a little further before responding!

For what is worth I used a 45 on the pump feed and a 90 degree on the reservoir feed fitting. I’ve had no issues with the push lock slipping with the short feed line. That includes when I dropped the transmission about a month ago to do the clutch. I was shaking and pivoting the whole engine assembly trying to back the bell housing off. Still tight with no leaks. And seriously do take your time bleeding any air out of the system. I totally ruined the first pump I replaced on my Montero years ago because I didn’t bleed it properly.

Ah, yea might want a bit more length to that feed line than me if that’s the case. I wonder if anybody makes a quality swivel fitting that would work for this application….
On second thought don’t do that
just follow Blaine’s advice! Hopefully you don’t go through several pumps like me!
They do, or at least they did, make an aluminum piggy back res that mounts to their 4.0 version of the pump. I ran one for years - and got it specifically because with the supercharger I had trouble getting a remote res in a position to get a good angle on the input hose.
OP
I am thinking the master cylinder mount may be the way to go in my situation. A 4 cyl has a lot less distance to the pump from there than a 6cyl. If I move the resi in front of the pump I would need a 90* possibly a 120* fitting at the pump. I will measure the distance to see what the feed line length will be. Also have to check to see if I still have the bracket.
Looking back at your original pics, it reminded me that my original install with a remote res had a nasty S-turn in the input hose to make a connection. If memory serves, I smoked two pumps that way.
OP
The master cylinder is a no go. My charcoal/evap stuff is there with no where else to put it. Maybe another 90* at the pump will help. The feed line hose length is very short. I will see what I can do with another 90* fitting. 
I've made the mistake of going straight at the pump or perpendicular to long axis of the motor before. This was on a pump with a pressed in fitting. The motor torquing over eventually pulled that fitting out the the pump. That's how I learned not to do that.
The push locks don't slip, you'll break the fitting or rip the hose first most likely.
If you can keep the hose length in -12 under roughly 18" and mostly straight, that will be good enough we can say it isn't causing the problem.
OP
Fitment is the issue, as with all builds. Hopefully I can fit about a 8” hose with a slight curve.
OP
If I switch places with my wiper reservoir and steer resi and add a 90* fitting at the pump I think all will be well. Will end up with a short straight run that will allow the hose to move with the engine. Resi will have to be lowered a tad but should still be plenty high.
Exactly what happened to mine in same location . Hose too short and engine movement had the hose seeping. I moved the reservoir back and lengthened the hose a few inches and zero issues since.
Noted, I’ll be lengthening the hose and moving my res when I install this new pump.
Just got this new fluid that PSC sent me. No clue how much it improves pump noise yet but I’ll be flushing my system and refilling with this sometime in the next few weeks. I’ll let you know if it helps with pump noise like the bottle claims.
Edit: I’ll also be replacing the pump and lengthening my feed hose at the same time so it’s likely going to be a combination of factors that fix my issues.
OP
They didn’t suggest any different fluid for my location. I will be optimizing my hose routing and connections as per Blaine’s recommendation. Everything shows it arrived at my house yesterday except a couple more pushlock fittings.
Hopefully will have everything this weekend.

Got the new pump installed. Moving the reservoir and replacing fittings.
I thought it was recommended to lock tight the adapter fittings into the cooler? Is that correct?
New aluminum pulley is cooler. Lol

We use red 271 or equivalent to lock the adapters into the cooler and the reservoir. Stops all the bullshit.
