I have a Big Easy turkey frier. I used to use a propane tank to fuel it. Now I have a large 120 gallon tank for my house I want to use, because I don't have the small tank any more. I have a regular grill hooked up to the house tank currently. My question is can I just take it off my current grill and go straight into the Big easy? Will I need the regulator on the big easy or is it regulated at the tank? I M pretty sure I don't need the regulator but I figure better safe then sorry.
