Thanks. I appreciate that you have experienced this problem before, as opposed to the numerous and sometimes random suggestions I have gotten.
I am making a list of items to check, and if low cost (under $25 each), will replace one by one. I don't have the capability to check the vacuum tank, but will check how easy it is to remove, and maybe take it somewhere or replace it down the road.
Will keep this post alive as I progress over the next few months.
