Our team is a first year team so everything we do we try to make extreemly simple. We found that if we took the following steps we eliminated most leaks.

1)connect as few items as possible and slowly add each time through (pump with 1 tank, pump with 2 tanks, etc.)
2) pressurize system up to 100+ psi.
3)Then shut off everything and make sure the room is totally silent.
4) have people on each side of the neumatics listen. You can hear any significant leaks and there easy to pinpoint by simply placing your finger near the connection and listening for a change in sound.
5) fix leaky connections starting clossest to the pump and moving away. Repressurizing after every 1-3 fixes.

This of course assumes you can get your pump to go up to these pressures. If you can't hit this high of a pressure then going through this process may also find where you're loosing it all. We orriginally had the problem of maxing at 30-40psi. When we did this we noticed that there was a spot that had come disconnected just enough to lose almost all our pressure but still 'looked' connected.
