After looking in my Bentley for some "casual" reading, I discovered that the plastic canisters located in the front wheel wells are expansion tanks and not charcoal canisters.  That device is located elsewhere in the system.  I didn't replace those lines.  I hope they're okay as I DO NOT want to remove the tank again.

Sorry,
