How are spring lock fuel line fittings made?

The fuel lines I'm working with are from the 90's, and are the springlock type with nylon tubing for the fuel line.

How is the nylon tubing attached to the fitting?

I can buy the nylon tubing to make some custom hoses, but I have no idea how to use it.

I've never taken one aprt, but they almost look like they are heat shrinked onto the barb.

You heat the end of the nylon tubing in hot water, then push it onto the barb quickly and forcefully.
Those aren't spring-loc's. Don't they have the nylon locking clip in them?
Dorman makes all the repair parts and you can get tubing in rolls also.
I did that when I eliminated the front tank on my 89 F350 Diesel.
