Charcoal Cannister Repair Replacement | Toyota Camry 1995 | [This is why my gas tank was leaking!]

I had a gas tank leaking from the bottom. Originally it was thought to be caused from a rear-end crash the client suffered a few months prior. After discovering the excessive pressure building in the gas tank, and asking the client about it, we realized the gas tank was not venting it's gasses properly. This happened to be the problem in our case but there are several parts in this system that could have caused such an issue.
