I'm using the John Guest fittings too. Really easy to manage. I don't know how long it's been since I installed the new lines but I should clean them... it's maybe been 5-6 months.
Do you keep spare equipment on hand?
What I do when things like this pop up, is start replacing things one at a time to try to isolate the issue. If you have another regulator and CO2 tank, give that a try. If you have more beerline, try replacing one line. If you have a spare faucet, replace one and give it a try. If you have a spare quick disconnect, try replacing that, etc.
For each piece of hardware that is involved, try replacing it one at a time to figure things out. You may need to even check your poppets, dip tubes, etc.
I changed out my tubing to the same bev seal ultra 235 tubing that they are talking about. I also upgraded just about everything to John Guest fittings, so connecting and disconnecting anything related to tubing is really easy now. I have these fittings on my disconnects, my shanks, my regulators, manifolds, etc. This tubing is great, and I consider it a lifetime tubing if I do my part in handling it well and cleaning it regularly (though, it has been over a year since I've installed it, and I haven't cleaned it since then).
Tap tear down and replacement....
