Another thing I noticed.

The bottom of my can has something similar to a small nail through a hole in the bottom near the edge. This seems weird but could it be a pressure relief of some kind? e.g. in the event of a large backfire the nail would fly out and prevent the can from exploding?

I bought the reservoir used of course so I don't know the history. The "nail" doesn't look like a normal nail, almost like its a special built nail for the purpose. Anyone seen this on another factory reservoir?

It seems to be preventing a good seal at this point (the can is holding pressure if I put my finger over the nail's hole).
