Backpressure issues w/Hydratech

[67MAL]

I had my low press return "T"ed into the line between my steering gear and cooler and was experincing
simular problems you describe. I moved the Tee to the line between the cooler and reservoir and solved my problems. Has worked great since, over 6000 miles. I'm also using a stock LS1 pump, although I may
have a different cap than you. The temporary bleed line that Paul mentioned sounds like a good way to
check.
