If you understand the boiling point of moisture while under vacuum, use compressed air. If not, try other methods. Use common sense though, if you have a stream of moisture coming out of your air nozzle, move on to another method or set up an inline filter/drain the tank and line.

Never had a problem using compressed air, and do use nitrogen occasionally to test for shaft seal leaks while submerging the compressor in water.

I've seen systems that leak under pressure but don't under vacuum. When you suck it down, the o-rings contract sealing it up, but when you pressurize the system, they return to a state where they leak.

100PSI will find your leak just fine.
