Hi zazbnf, I haven't done this yet, but was thinking of bring my "Guinness" keg to a family reunion this weekend. Also I have my taps apart due to a blown compressor. I'm making a new keezer.
The question is, what is the purpose of the "1 - 3/4" piece 5/8 OD plastic tubing (Fits inside larger tubing to reduce id for picnic tap.)"? It seems like the larger tube is the one that is clamped and where the beer goes through a restrictor anyway, I was wondering why you even need the inside tube. Or is that to keep the O-ring seated? I think the O-ring is usually screwed in place. Also my stout faucet is metal. I wonder if that makes a difference. I believe there are indents in the faucet for a wrench.
