I only have two taps with this system and I've got the Double Gauge - CO2 Primary - Premium Series regulator, per the micromatic website: (
http://www.micromatic.com/draft-keg-...s-pid-642.html), except, as opposed to the one pictured, mine has two 5/16" outlet barbs; they are, as pictured, to which I've affixed the gas hoses and clamped them not with the Oetiker clamp but with some white plastic clamps that I had to push shut with pliers (perhaps I should chuck these and go to homedepot and get more Oetiker clamps?); the same arrangement is at the other end at the tank which connect by Ball-Lock connectors with the same 5/16" barbs. There's no real manifold as I've just got the two barbs from the regulator.
I told my CO2 leak story to the guy as the gas place and he suggested the washers for the tank to regulator connection, so I've got that in place and I did really bear down this time.
I do like the pipet idea so I'll give that a shot and I won't dunk the regulator; though I may test some of the gauge connections, etc., if this thing runs out again.
Thanks for the advice...
