just remember every time you introduce a fitting or adapter its another possible leak point. after going thru the conversions to an and custom hose ends etc and finding leaks after running wrenching here and there i finally punted and went standard stock.

I went to my local hose shop and had long runs made (so I could move them around) with stock GM O-ring ends crimped on each end and done.

don't change flow or pressure until you get it all plumbed up and checked out.
its easy to change that one fitting or shims if needed in the pump.
