Mike R.,

He used what appeared to be proper mainfold gages (two in tandem), but he only connected one side. The third end went to tank of R12. Which he opened at least once.

Is it possible that the readings are not correct unless they are both connected. Not sure if that makes sense to me.

Hmmm, are you saying that I could check the presure myself with a tire gage? How high will the high side be in lbs/in^2?

Thanks,
