Ok, I figured out my problem... I didnt realize there is no tool for this type of connector and that it is removable by hand by suppressing the clip into the fitting and pulling it off the rail.
BUT, my new problem is that I broke the old clips the manual says to replace the whole line and not to try to replace just the clip but the whole line is discontinued at the dealer! Can I still get the clip out? or can I cut my gas line and splice the whole fitting onto it?
