I received a like new Performer grill with the touch-and-go gas ignition for lighting the charcoal from my cousin when her husband suddenly passed. Came with everything, like cover, owners manual, and tank fill adapter...plus a full tank of gas. I finally got around to using it for the second time in several years to do some pastrami smoking this weekend. Turned out excellent, although I need a bit of work on regulating vents for temperature. Grill works perfect and ignites the charcoal just as it says in the manual. My concern is what happens when the tank runs out of propane. It is a 5lb tank with the new type ODP valve and I do have the adapter to fill it. This tank has the 1/4" quick connect fitting and attaches to a male 1/4" quick connect fitting at the regulator in the grill. I'm concerned I may not be able to get the tank filled because of date certification, even though the tank is in excellent condition. If I can't get it filled what are my options? I contacted Weber about using a 20lb tank/hose hookup and they suggested a hose that has a 1lb connector on the end opposite the tank hookup. Obviously that will not fit the male 1/4" quick connect fitting coming out of the regulator in the grill. I was able to find a hose with the acme hookup for the tank and a 1/4" quick connect on the other end, BUT it has a regulator on it. My understanding is this might be a problem, since there is already a regulator in the grill. I have spent several hours looking for some type of hose and or fittings that might work, but to no avail. Any suggestions from anyone as I'm sure someone has experienced this problem before? Any help or suggestions would be much appreciated.
