My 57 Skyliner has a gas tank which stretches across the width of the car. It is fairly deep and not very wide front to back. Also in the middle of the tank width wise, the the bottom rises almost half way up the depth of the tank. This to clear the driveshaft. I am wondering how the gas gets from one side to the other after the level goes below the arch in the middle of the bottom. When I was working on the sender I noticed that there were two steel tubes on the bottom. I am wondering if one tube is used as a siphon.

Here's one.

Depending on the side of pick up on. Maybe just sloshing of hard left and right turns allows most of the gas to move from one side to the other.
I often wondered about that myself. And Abe, for the gas to be able to "slosh" from one side to the other, would likely require some pretty reckless driving, the 2 side chambers are separated by a pretty large wall.
So my thinking right now is that there is a tube that is either used as a syphon or there is aan outlet fed by a tube from each side.
.
I was think I'm g a tube also but didn't see it on the pic you posted. Or maybe dual pickups for the fuel lines.
The tank has a "T" to pick up fuel from both sides. Not sure how it acts when the tank is nearly empty?
Oh OK , that is really interesting. Thanks for that information.
