I recently replaced my fuel pump and after starting the car noticed gas all over the ground. Slid underneath to investigate and noticed that this return line for fuel was disconnected (blue circle), I’m guessing me moving tank around disconnected it.
I reattached it and it seems secure, but is there a clip that goes in that slot? I see the clips on the hoses where they attach to the tank but this slot appears much thinner and doesn’t look like the same attachment method, but I don’t know.
if there is a clip is it specific to Jaguar or can a cir-clip substitute?
On the hose connections on the tank there are two clips that secure those lines, and I see in the above thread the links for new clips.
The fuel line in my pic is the flexible return line next to the fuel filter. And after looking at it, I don't think it has any type of external clip. It looks just like the fuel lines in the engine compartment. pics to follow
Those don't use clips. Note how close the machined fitting is to the formed bead on the tube. The one at the fuel tank needs to be pushed on that far.

Question. If the fuel line connectoin is just pushed in, what is preventing it from disconnecting itself? There must be some sort of lock on the inside to prevent it from coming loose.
If you had to disconnect the fuel line, there has to be a tool that slides inside the connection to release it; a la Ford and some GM fuel line connectors.
To Bullittandy. How did you disconnect that fuel line in the first place? That should give you an idea of how it is put together?
I think it is called a LEGRIS connector. The one without the clip is released by pushing it in then pulling it out. If it has corrosion it will be a bear to release.

No tool I'm aware of, and I looked. And yes, they can be a bear to get off.

I (inadverdently) disconnected it by man-handling the fuel tank while replacing the fuel pump. But I think it was previously disturbed by someone working on a section of rubber fuel line right next to it and they didn't securely reconnect. And when I was moving tank around, it came apart. Since I reconnected it, it appears secure.
It looks to be a Sharkbite type connection. They make tools to help remove them, maybe one of them will fit the fuel line?
That is a good description of how they appear to work. But I cannot imagine how difficult they must be to remove after the sliding portion has been subjected to decades of dirt, debris and water.
And I'm wondering if that's how mine disconnected, previous person got it to slide enough to release but it didn't "spring back" and while the pipe was connected, the connection remained open, like a closed, but unlatched door.

They are quite hard to push back as shown in the depiction in post #8. Especially the one in front of the left rear tire where the fuel filter is located. There are spring loaded stainless fingers inside which lock the fitting to the lip (#2). By pushing that collar back enough, the fingers get pushed up and release the lock. Road grime does collect and make it hard to unlock. Some thorough cleaning with a brake or carb cleaner and compressed air does help to dislodge some of it. Unfortunately, Jaguar didn't give them a few extra inches to slide the tank out far enough. I usually just slide the right hand side of the tank far enough to gain access to the pumps and try to avoid to put to much strain on the lines exiting the tank at the bottom front left side of the tank. The stainless line already has lost all of it's rubber coating as shown in the picture of the Legris fitting in the engine bay. Makes me believe somebody was already in there. The Jaguar shop manual actually want's you to disconnect the lines at the bulkhead fitting up in there.
