As usual, I agree with Paul.
These are pretty forgiving and durable components, many still fine going over 40 years!
They typically are abused by well meaning attempts to "top off" the tank.
When you do this it floods the lines with liquid fuel which can make it's way to the canister.
The canister is designed to handle vapors and does so very effectively.
Drowning it in liquid often results in complaints of fuel odors in the garage, with no apparent leaks.
The liquid will eventually vaporize, or be drawn into the engine
I used to always top off the tank as well, but having witnessed this recurring owner or attendant induced problem, have finally given up the practice.
It also wastes most all of the fuel that flooded the lines and canister.
When the pump clicks off; The tank is full enough.
While not really a tree hugger, this is a simple but effective way we can all passively help the environment.
