wow i could have used this about a week ago. i only broke 1 before i figured it out.

 

Thanks to the OP for this handy guide. I managed to break one of my quick connectors while I was dropping the fuel tank. It is similar the to one pictured in the 6th photo down from the top.
A two piece connector where the black part that you squeeze latches into a translucent plastic part that contains the o-ring seal. It is for a the vapor return line on the very back / top side of the tank in my 2010 Suburban.
Does anyone know where to source one of the parts? I don't really want to replace the whole line. If I had to guess I would say this is a dealer only part,


This is the part I am looking for...

 

We don't have information about Suburban here. These forums are for the Chevy HHR.

The dealer would be a good starting point, hopefully they can at least give you a part number.

 

Try you local parts palaces, Dorman might offer a solution, measure the OD of the vapour line it should be either 10 mm or 3/8 inch or 8 mm or 5/16 inch
