Is this a Flex Fuel vehicle?
For the Flex Fuel fuel filter, you will need a special tool: J-46363 Fuel Line Release Tool. You can usually rent (or even buy cheap enough) this tool from any local parts store.
Using a flare nut wrench and backup wrench disconnect the fuel line fitting from the fuel filter.
While holding the filter, push the fitting towards the filter in order to disconnect the quick connect fitting.
Remove the fitting from the filter.
