It is just a spare connection. You can just blank it off.

If you had a coil in the cylinder you would have 2x 1" Male Iron threads about 1" long sticking out from the side of the cylinder, one above the other (usually) and about 15" apart.

Are you sure the top hole isn't for an overflow pipe? Some cylinders do have them just in case they over-fill.
