Alright, I decided to brew toda. Mashing an the first 30 minutes of the boil went well, no hitches. At 30 minutes left, my propane tank ran out of juice. I went to the nearest exchange, got my new tank, and came back and hooked it up. However, it wouldnt let gas come out. I went to the station and got another one, saying there was an issue with the first. This one wont work either. I'm not sure what I'm doing wrong, I have never had this problem in any of the other 10 brews. I've uploaded some photos to help troubleshoot. I need to get this solved so i can finish brewing and make dinner for the fiance!
