49TT - Sorry to hear of your run in with the hit and run driver and the physical injuries.
Glad though to hear you are still with us and on the mend!
On your topic of "follow" options, you need to look at and update your "Preferences" and "Follow Lists" (under your member name) so you can get notifications when folks reply to your threads or in a forum you are following. Send me a PM if you need more details.
I'll leave the answering of the "vacuum tanks?" question to other Big Bolters that are more familiar with that equipment.
