Before I discarded my original 1970 California gas tank I cut it open to reveal the inside. I was surprised at the inside of the tank. (By the way, the tank had been purged, sitting open for 6 months, etc. so I was NOT trying to live dangerously...)
The four vent tubes from the tank go to a recovery tube that is installed in the trunk. This tube is fed by a line that runs from the engine compartment and is intended to recover gas fumes.
I knew that the CA tanks had a separate little tank inside. My assumption was that at least one of the vent tubes connected to that tank. I was surprised to find that none of them did. I know that reproduction tanks do not have this separate little tank. My question is, what was its function? I can't quite understand what the benefit of having that little tank would have been since it is not connected to anything...
