Take a look at this pic, this came off a thread from another forum.

I did this mod, it makes using the Weber so much easier. In my case I did not do 1/8" quick releases as my RV dealer had 1/4" which seem to be easier to come by, this just meant I needed to get a reducer/coupler 1/4" to 1/8". You do not have to get the parts online (maybe cheaper though). Lowes carry the gas tape and coupler (in the gas fittings section). The quick release's and hose will likely be found at most RV dealers.
