M.B. Sturgis Inc.1/2" ID Gas Grill Quick Disconnect Gas Connector Kit (8 Feet)

Want to go from 10' to 30' on my weber ng grill. is that length okay and does weber use 1/2" or 3/8". looks like 1/2"

Weber genesis ii s-310 ng ss - will this work as a replacement?

Is 1/2" x 30 feet sufficient diameter to support a 6kw generator? based upon btu rating, i assume its plenty, btu to kw may not apply for engine use

Is this the correct sized replacement to fit a natural gas pre-2011 Broilmaster Body Style 3?
