Is a reservoir 'Air tank' needed for bagging? The System I purchased from CST did not have one, but I noticed the system from ACP does have one. Does having a reservoir make the pump work 'less' ? Or does a reservoir allow a weaker pump to pull more vacuum, (Like having a 'vacuum amplifier' connected to the system) ? My pump seems to pull as much vacuum as the gauge can take. Any 'advantage' to adding a reservoir? Jeff Winder [EMAIL PROTECTED] RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
