By law, when a propane tank reaches 12 years of age, it can no longer be filled. We see this frequently at our propane platform here in Peabody, and with the Fourth of July weekend coming up, we figured weâd share with you how to tell whether your grill tank is out of date.he only thing youâll need is the manufacturing date. As of the day of this post, any tank with a manufacture date before 07-01 we would not be able to fill. If a tank is more then 12 years old, it cannot be filled.
