I re-read my last post, and it looks like I need to re-write. I was going to say, "I'm wondering if it would be better served to run it through a PS cooler before going back to pump."
Now, I'm in a dilemna with my project. My PS pump only has one high pressure out, and one return, which is molded into a plastic housing.
I'm going have to rethink How I'm doing things now.
