How do you remove the fuel filter on a 1994 Chrysler lhs There is no nuts and bolts just a funny looking connector how does the special tool work and how do you take the filter off?

If the connector looks like a swelling in the line and the "special tool" is in 2 pieces that goes around the line, put it around the line and push it into the coupling. Which ever side it will go into. This release's the inside clip holding the filter. Another type of fitting just pushes in with a clip that goes over the coupling to hold it on. Remove clip and pull apart.
