auxiliary tank question

[cdkaminsky]

I was looking at my aux. tank...to get an idea of what I need to do when I install my new floorpans.

I was wondering what the tube at the top center is....

The sending unit is at the bottom center, then the vent hose, then the filler hose.....then I have another metal part sticking out that has a rubber cap on it.

I am not sure what this is.....

Could be another vent for the charcoal canister??

thanks

Could be another vent for the charcoal canister??

I will just have to examin it when I drop the tank.....the end is flared and is about the same size of the piece (diam.) for the fuel line on the sending unit.
