I have ran across this connector on an EVAP line at the fuel filler tube in a dodge 2004 ram 4x4. How do I get it apart? I need to drop the fuel tank to put in a new fuel pump, but this line needs to be disconnected in order to do so. I've looked all over the dodge forums, but maybe you guys know what it is.

I guess I don't have enough posts to post attachments?? You can see my pictures here: Fuel pump install, special tool for vent hose connector? - The Dodge Truck Forum

Thanks.
