[b]captnem:

You started out correctly, using a single tank with separate clunks for each engine. From that point though, it's almost impossible to get satisfactory results with an ordinary muffler pressure system.

My way is a Perry VP-30 pump on each engine, although the Cline (or Iron Bay) regulators will also work, as suggested by Tmoth4.

Final note - the Perry system costs about 1/2 the price of using Cline or Iron Bay.
