If your "smelling" strong odor your tanks below 20% and the "odorant" in the propane gets very strong like a dead mouse smells.
If you suspect a leak you need to use a bubbling solution to locate the leak in your pipe, and repipe dope/repair the leak. Have been reading other posts and if you guy's out there are not licensed and properly trained to work on gas heating equipment, call your propane company and get someone who does. This is not something to get knowledge or lack of, to do it yourself!!
Equipment that is "old" and or new and you got an odor you need to address it asap. When you get your propane bill it tells you what to do when you smell propane!
These are our beloved garages, they go up in flames real quick, Please do not mess around
