So I've been looking at either buying or fabricating a replacement gas tank for my bike, and I really like the style that straddles down on both sides of my bike frame (for example, Sachs Tanks | Ghent Cruisers). But it seems like the gasoline on the "far" side of the tank (the side away from the fuel line outlet) wouldn't be able to drain out of the tank. Is the "far" side of the tank filled in somehow, so that fuel doesn't pool uselessly in that side? If not, when you start to run low on gas, do you have to sort of slosh the gas over towards the side with the fuel line? I'm attaching a diagram to help explain my question. This is an "end-on" view of my future gas tank, looking from front to rear. Thanks!!
