David E Hesperia , CA February 14, 2020 I was unable to take the fitting of the old regulator to change it from 1/2 to 3/4 It became more complicated when I could not find a 3/4 to 3/4 gas line. Also I needed to order the gas line and buy another fitting because the new regulator had different size ports. However after was said and done it all came together without a leak.
