12 hours is really good. Although Michael was dead on with looking for a leak at the HCV, I doubt the HCV is the culprit with pressure staying up. The HCV supply is from the supply side. The supply side of the HCV does not tie into the sixpack and the HCV has pressure if there is pressure in the supply. The outlet of the HCV connects to the sixpack, and the sixpack connects to the air bags.
