Thanks. The smoke machine has a regulator on it that only allows a 0.5lb output so that it can be used for Evap leaks. The instructions say that you can hook up an air compressor with a max output of 200 psi to the machine but I won't be using anything with that much psi.Nice stuff, make sure the turn the compressor regulator psi down for the smoke machine to about 1-2 psi or better yet hook a hand pump up to it with a fitting when looking for evap leaks.
