Gone through two tanks too fast so I made sure I screwed the valve to the tank tight so it must be leaking at other end. I look under and it's not a screw in type (crimped line). I guess I need a new hose/ reg. assy. Model 463666507. Less than a year old. Paid roughly 80 bucks at Lowes. How do I fixed this w/o spending 70 bucks on a new Valve/Hose/Regulator, p/n 80005802. Thanks.
