There is a special tool for this, seen it mentioned here before. Supposed to be available at most auto parts stores.

I am trying to replace the fuel filter but am having difficulty removing

> connector that seems to be just pushed on over the little ridge that is
> on each side of the filters inlet and outlet lines. I have tried pulling
> it off by hand as well as using pliers, however it won't seem to budge
> and I am afraid of breaking the connector.

> Anyone have any clue how to remove the fuel lines?
