One of the reasons we got a new two burner grill was because the old Weber is about rusted out, though still useable. The new Cuisinart (recommended by ncnascarlady, who had a similar one years back) worked fine the first four times we used it, but then stopped working. I had purchased an in-line fuel gauge so I would not get caught out by a low tank as I was recently. I put the gauge in the line, and those four times everything worked. I figured Step One was to take the gauge out of the line and hook directly into the tank and see what happened. The Cuisinart fired right up. Okay, so I have the grill working again. But why would it work fine with a brand new tank with no muck in the threads or the feeds of the gauge, then stop working?
