There is a cannister on my 72 cj5 located next to the fuel tank on the driver side. What is this? Is it a basic charcoal cannister or is it some type of rollover fuel protection device? I am in the process of learning everything about my jeep and have recently replaced the fuel sending unit and probably made some mistakes. I assumed the device is a basic charcoal cannister to absorb fumes but now after having to reassemble everything and not remembering where everything goes I do not want to take the device out of the picture if it is IMPORTANT to my vehicle.
Thanks.
