I hope someone can help. My Vacuum system intermintently cuts out. It quits for two days and then mysteriously starts working again. I checked for vacuum pressure directly from the pump and it seemed low. What should the vacuum pressure be coming right out of the pump w/no accesories? Also, if it is the pump (perhaps a valve is sticking intermintently) is the rebuild a usually pretty reliable fix for most pump related problems.
