Anyone on here use the sap puller diaphram type pumps for your vacuum system? was wondering how they would work for 250 taps.

There are several threads on this list about Sap Pullers. Do a search. In general they work alright if your system is tight. Max vacuum is 15-16" Hg. They don't move much CFM, so even small leaks will cause a vacuum loss.
