It sounds like you're needing a whole new mounting kit for the propane tanks on your 2012 Jayco Jay Feather 23B:
- Complete Propane Tank Holder Mounting Kit for 20-lb Tanks # 37220BL
- Complete Propane Tank Holder Mounting Kit for 30-lb Tanks # 37230BL
You just need to source the mounting hardware and then you should be able to reuse the mounting bracket for your regulator and you'll be good to go! view full answer...
