Here's a pic of the inside of a 1969 B Body tank

Took a pic of my fuel tank to figure out where all the vents go. Figured I would paste it here for those that are interested.
Note, the two vents on the left in the pic, One stops at the back of the tank and the other goes all the way to the front near the filler tube,
The second, (Fuel return i think) is attached to the pickup tube and sending unit, it ends up getting covered when the tank is 1/2 full.

For Context, my '69 Bee has been sitting for 30 years I was worried my tank would be a mess of rust. Everything looks great. You can see the fuel level line, I pumped out about 5 gallons.

That’s helpful to have posted.

Shouldnt the pickup be very close or touching the bottom?
