Turns out it was not the pump internals. This time it was the crank pulley grinding into the water pump pulley!!! They ate so close together they actually rub each other.
I fixed the problem by running the engine with the car up on the lift, with the pulleys grinding against each other making a horrible noise.

I used my Dewalt angle grinder with a 40 grit flapper wheel to grind off most of the outer crank pulley flange until the noise went away. 

This is just a very sorry design. There should be at least 1/8” clearance between two rotating parts.

The worst part of the whole thing is all of it is held on with just four 5/16” bolts with nothing secured to the heads.  I will never again put money into something so ill-conceived.  Part of the problem was buying it based on pictures rather than seeing it in person first.

If you need good custom brackets, duplicate what RPM did on his car. Simple, sturdy and very effective.

Just out of curiosity perhaps RPM could refresh our memories with pict of his set up.
I’d like to admire his skills.🤩

Just measured the distance between my pulleys and it is .067". That is not a lot of room between pulleys.

 
Not much but more than enough, can’t see any circumstance that will make them clash.

Thank you Steve for the kind words.

My AC and alternator brackets ain't pretty Rudi, but they seem to work just fine. They are made from 1x¼ inch flat bar, and ¼ inch plate.

Well done Bob. So basically simple yet totally efficient, unlike  a lot of over engineered, over priced products out there that don’t work.

Wow, I considered going to a sepentine belt system, now I'm glad I stayed with V-Belts. 

 
I really like the V belt look much much more than serpentine belt.

The circumstances that makes the pulleys hit is if a new water pump is installed and there is enough slop in the water pump mounting holes for it to slip down 0.068” before the bolts are tightened.

The pulleys did not interfere with the CVF supplied water pump or the Ford Racing water pump. Interference started when I installed the Made in USA Tuff Stuff water pump. There was significant interference.

Steve, have you thought about an electric water pump. You could probably get a good deal on an electric water pump and electric fan combo. I'm gonna go duck down behind this wall

#8 and #10 in picture refers to the refrigerant line size.

3/4” and 7/8” in picture refers to the fitting thread size.
