: Fuel tank mysteries

I have been told that if you're low on gas (like < 1/8 left), do not idle the engine for any time with the vehicle facing down hill, because the fuel pickup point is towards the rear of the tank. Has anyone else heard this?

I left the vehicle idling facing steeply downhill once when low on fuel, and the engine quit in about 10 minutes. I rolled down to a level spot and the engine started immediately. Then I went for gas right away.

I'd like to know more about the gas tank, fuel pump, etc, and exactly how it works. Anyone have a diagram of that area?

This is a common with many of the GM models..I've has the exact same thing happen to a Saturn Minivan we once owned.
