Our team had slight problems related, but this was because we made a variable pressure kicking system using a couple values and somewhat complicated arrangement of plugging in hoses to slots in the valves.

To solve the losing pressure I would start off with checking to make sure all the tubes are long enough to fit in the valves with space, also make sure that the hoses are fully inside the valves or quick-connects in your pneumatic system. Then from there, if you are still losing pressure, well if your losing pressure from the exhaust then your plugging of the valves isn't done correctly.

Hope I Somewhat helped. I know that pneumatics can be a pain.
