Brian if your future plan is to have 2000 taps it would be well worth the investment to purchase a double releaser. New or used. They are very reliable and operate on higher than 15-18" vac. You won't regret it. That being said, yes 250*300 taps is probably the max, yet I had 800 on the larger Bender and 400 on the small jar. If you max them out you tend to have sap backing up unless you create a manifold ahead of your Bender. There are some previous posts and pics in March 2012 here on the Trader.
