My new camper came with this. Looks like someone used adjustable pliers the last few (several?) times to hook up the propane tank. Given the amount of tape I'm a bit hesitant to touch it until I need to--but I'm not sure how much is in the tank, so I should fix this sooner than later. Ideally I'd like to use an OPD fitting. Simply easier than using wrenches. Should I replace the regulator, or do they make a fitting that does this for me?
