Ok Rusty, now you have me a little confused.  Your rev-2 upgrade seems a lot like my current system.  A pressure cap (rev-2) at the rear side housing outlet (highest point in the system) is just like having a small tank there with a pressure cap on it (my current system).  I would prefer not to make the change if you think there is nothing wrong with the current system and my problem lies elsewhere.  To AST or not to AST, that is the question. 
 
Sorry Dave, I think I wasn't very clear about where my new pressure cap is.  It's at the top of the water pump housing, as you can see in the pic.  The way I had it in the rev-1 arrangement is actually more ideal, but I ruined it with some large loops of hose that tended to trap air.  That's probably the only reason my rev-2 arrangement seems better.   I would urge you to continue with your proposed change.
 
Cheers,
Rusty (AST's are never bad, if you have room for them)
