I just bought a replacement battery for my Mini Cooper, a group-47 battery that fit perfectly. However, the vent tube wasn't long enough, and it did not come with a vent tube kit. So, I gave the vent tube a little tug and out it came.
How do I replace it? Do I just stick a new tube into the hole that it came out of and attach the other end to the battery? Also, not sure what size of hose I need, but that probably depends on the battery.

Thoughts? I am definitely not a mechanic.
