Why is my car spitting gas out?
The fuel vent hose on the fuel filler neck is plugged and not allowing the fuel to vent as the tank is filled up. Over time, fuel vapors with debris in them will plug up the vent tube and cause it to not vent the fuel tank. This will make the fuel system not fuel up under a heavy load.
How do gas pumps know when your tank is full?
When gasoline flows through the nozzle, it passes through something called a venturi, which is a tube with a narrow throat that changes the speed and pressure of the liquid passing through, creating a vacuum. As your gas tank fills, the fuel level rises until it covers the hole at the end of the nozzle.
Why does my gas tank overflow when filling?
