In my case though, I need the higher pressure for the Hydroboost, but then need to reduce it, so I had to buy the Heidts valve to be able to adjust he pressure to the rack as I like. It has been an adventure learning all this about the pump, hydorboost and a rack system .

You may want to look at the pressure info and specs again. The "typical" rack conversion that requires pressure reduction to ~800 psi is the old hot rodder favorite Pinto/Mustang II rack. The POL rack for our trucks is based on a mid-90's Dodge Dakota, and should be fine with the higher pressure. I emailed POL tech support and Erick confirmed that the higher pressure from the Saginaw-type pump was fine with their rack, no pressure reduction needed.
