Hi,
There are three different types of quick-connect fittings that are used to attach various fuel system components, lines, and tubes. There is a single-tab type, a two-tab type, or a plastic retainer ring type.
Take a look at the three pics I attached below and let me know which one appears to be the type used for your vehicle. Note: These fittings, in most cases, have an o-ring in them that can be easily damaged. So, be careful when removing and replacing them. Also, the o-ring should be lubricated with motor oil or even Vaseline to prevent damage.
I suspect you have the push-on type with the latch clip (pic 3) if it is on the rail, but I just want to be sure. Also, make sure you have released fuel pressure prior to disconnecting the system.
Let me know what I can do to help.
Take care,
Joe
