Tiko, Don't delete your cooler. That wasnt the suggestion. What you DO want, is the return from the HB to go directly to the top return port on the pump. You want as little back pressure as possible on the HB return. The return from the steering box should go through your cooler and to the bottom return port on the pump.
I have a astrovan HB I installed on my 75 F250 with saginaw pump and 35's , my steering is 1 finger while parked and the braking is very impressive. You'll get there.

One other thing on your diagram, it lists the pressure-in to the power steering box as being the large port. It should be the smaller port that is the pressure in.

I don't know which is larger vs smaller but that could be,.

Mine is a '76 and the diagram is correct. the in is the more forward one and return is towards the rear.

There is STILL one inaccurate HB plumbing diagram on our CB site that is incorrect. I'm still trying to help here... not going to comment, just posting up for others that might look this up for reference.

Got it rerouted like the diagram above. It’s definitely better! Not one hand palm turning at idle but not struggling turning at low speed. The brakes feel good.
Once again the site is proven to be the best around!
Thanks again guys!

Great idea, don’t want to remove the bad diagram because it shows what has happened….
But I made a note saying “ DO NOT USE”

Looking at the box
From over the top the inlet pressure port is the port closest to the inside, the return port is the one closest to the out of the box
So. IN = inside
OUT = outside

Didn't mean your diagram but a one that was being used a decade + ago & people were having issues with it

I did not take it personal, actually I thought it was a good idea.
Thanks to all that weighed in to help, I appreciate it. I was so ready to give up on it.
