How do you disconnect a quick connect gas line?

It depends on the type that is used. There appear to be at least 5 different kinds but the one used on Saabs needs a GM disconnect tool that you can purchase from Harbor Freight or Autozone for under $10 bucks. The Saab quick connect has a rubber stopper / bushing that fits into the end of the metal quick connector. The bushing's purpose is to keep debris and dirt from getting into the connector. To Disconnect a Saab fuel line from the Fuel Rail:

Grab one of the 3 rubber tabs that stick out perpendicularly on the side of the bushing and pull it toward the fuel rail. (You need to get the bushing up over the flair that keeps it in place.) All you want to do is get enough space between the bushing and connector so you can insert a small box wrench between them and use the wrench to pry the bushing up over the fuel line flaring.

Once you have the bushing up out of the way, insert the disconnect tool into the end of the quick connector and push the quick connector up toward the tool. (The tool looks kind of like a pair of scissors that when closed form a 3/8" tube on one end and a 5/16" tube on the other end...). There are 4 metal tabs inside the quick connector that bend inwards toward a flaring that prevent the connector from coming off. By pushing the connector onto the tool, it pushes the 4 tabs back out of the way so they won't get caught on the flaring when you attempt to pull the connector off the line.

With the connector pushed up onto the tube of the disconnect tube, you will then push both the connector and the tool away from the fuel rail. You might need to wiggle it back and forth but if you have the connector pushed up onto the tool far enough, it will provide enough clearance for the tabs to clear the flaring and the fuel line will disconnect from the fuel rail hard line.
