How the fuel filter is connected through a fuel pipe?
Some modern vehicles use an external fuel filter that is attached to the fuel supply line. This is connected to the gas tank and the fuel rail that feeds the fuel injectors. You can find the fuel filter simply by following the supply line.
What happens if you put your fuel filter in backwards?
