Fix the leak; 1 PSI loss per minute is easily achieved. Saves grief in queue, too.

Get a small cup of soapy water, pressurize the system, and paint the entire pneumatic system (with a 1/2" paintbrush) at every connection. Include the two connections on the compressor head, and the connections between parts of the pneumatic valves. Any bubbles that form and grow indicate leaks; tighten the connection/replace the teflon tape/cut the hose end square to stop the leak.
