WRONG!

This is just a personal opinion having attempted to deal with this... and ultimately failed!
I believe the hiss is caused by the design of the coupling.
Its metal to metal where it connects to the spline on the box
I don't believe the use of the setscrew helps this either.

If you don't buy this theory,
WIth the car idling in Neutral, put your stethoscope right on the end of the coupling past the set screw but not on the box...
You'll hear the same sound you hear in your passenger compartment just amplified...

This is just my opinion (I showed to several engineering friends of mine)
Their opinion was unanimous....
The coupler, while well meaning is a hack.

Yes, it "fits" but…. I personally feel it needs to be re-engineered to muffle out the sound where it connects to the spline
and it should use a roll pin just like factory....

WARNING: Don't buy his pump expecting it to fix anything.. it doesn't.
He's basically offering it as a try and see... (think about that for a second)
(in reality this entire setup is a try and see!)

If you switch to his pump pay very close attention to your mounting brackets..
If you have the 70-71 oval pump your brackets will NOT fit the newer style pump (although the look like they do!)
and everyone and his brother tells you they interchange....True, bolt holes all line up and as a result
the brackets bolt right up but watch the clearance on the front big bracket
to the housing of the pump...it will interfere when you tighten it completely down....

You will only discover this after you've removed your pump,
bought his, bolted it all together and then bam... you can't use it!

He may try to sell you a new bracket to mount your pump with....
Then you will discover (the hard way) two things

1) that the return outlet is larger than the stock outlet and in a different place.
So you will have to get a larger diameter return hose than your stock..
Hint: if you have a stock PS pump and return hose your stock clamps wont work either

2) The location of the return outlet is different on his pump vs your stock pump
so your return hose will not be in the same location
This will rear its ugly head only AFTER you bolt the new pump in and try to tighten the belt...

My recommendation... if it's hissing in your passenger compartment.
Remove everything, return it immediately, and get [ball][/b] of your money back.
Don't settle for this...

Again this is a personal opinion based on painful experience with this setup.
Rightly or wrongly this is NOT an engineered system for a MOPAR
It is a collection of parts that "fit"
It well meaning and well intentioned
and I deeply appreciate Mr. Bergman for attempting to address
what I think is absolutely the worst thing about old Mopars (the pinky power steering)

I give him further kudos as he did STAND behind his warranty
and did not hide behind it like so many other parts people do...

But... for the $$$$ I said forget it...
I say that with the utmost disappointment.. Because I personally wanted this to work BAD!!!!!
I did everything I could. ….

Hope this helps
