Hello Franky, Robert from Nexgrill here. Thank you for providing feedback on the conversion process. You are correct, this kit is 1/2 but most of our customer's home are 1/2. It also sounds like your bi-passed the regulator and your home is already regulated. For those cases we do sell a 3/8 inch hose and quick connect available here at Home Depot which would have made it easier for you. This kit is used on a lot of different grills, so the regulator will not attach to all grills, but it is ok to let it hang. Since not all grills are convertible, orifices always comes with the grill if it is convertible. If you look up precision screw drivers on Home Depot, you can find several inexpensive sets that will work with the grill. I hope this answered a lot of your questions. We also have a Youtube channel that you can check out. https://www.youtube.com/channel/UCC7_yR1HnlWaJNT_TpAzcYQ/feed Happy Grilling!!!-Nexgrill
