It'* your return fuel line connector. You probably squeezed it just enough for the connection to break and leak a little fuel(which is normal) Of course, it depends on what you tried to "disconnect" it with. What did you try to disconnect it with?

Oh ok. Do you mean like what did I use? I didn't use any tools I just used my hands. I kept checking and it doesn't seem to have any cracks or anything so I assumed I didn't break it but I just couldn't get it to click back into place.

I had the same issue with that fuel line, the o-rings in there fail, and if they have failed you can barely press down on that fuel line, and it will leak, you need to get the o-rings in there replaced, there are two of them, and the innermost is tough to get back in once you get it out, you'll need a pick set to help get them out, and back in.
You are supposed to remove that fuel line after relieving the fuel pressure, unless you bungee the fuel rail up to the hood.
I removed mine to avoid kinking the nylon fuel hose in any way.

We have an old thread here somewhere that has the part numbers for the correct fuel line o-rings, I'll see if I can find it.

I am unable to find the exact o-ring part number, but here is a link to the set of picks I bought to help remove the o-rings.

Found a few threads with the same issue, here one thread says that when you out pressure on it that it is normal for it to leak, mine was leaking whenever I'h hit bumps or anything, and the rail was yellowed a bit from all the gas leaking out occasionally, so I had to replace the lines myself, tried to get the innermost o-ring back in and just could not do it for some reason.

Oh ok, thanks! How hard was it to replace the line?

depends how much of the line, it transitions to metal before it goes under the car. if you are in a area they use salt, i am a fan of replacing them all with plastic. they have plastic to threaded adapters for the filter and at the top of the tank

Thanks for the link. I am going to try and replace the o-rings and hopefully fix it like that. Hopefully I won't have to end up replacing the line.

Hope replacing them goes well for you, I was forced to replace mine, as I could not get the innermost o-ring into place, so I was forced to run rubber fuel injector hose that is made to handle the psi, and use hose clamps, eventually I plan to try to replace the line with nylon from the hard metal line, like it was originally, I just have to find an easier way to bend the tubing at the end where that attaches to the fuel rail, I may have to warm the line, and try to bend it into shape while inside, as it is tough to warm the line up enough to slide it over the metal part of the line at the firewall.

I have heard of a few people getting lucky and replacing them easily, so hopefully it goes easy for you as well.

you use hot water to warm the nylon, i used a coffee cup full for doing the connectors, if you need to bend it you could find a pot or something to put more of the line in. your results with your significant other may vary, i had to get my own yard sale cookware and cups to save me head pain

Maybe the water needs to be boiling, because I tried hot water that was hot, but not quite to the point of boiling, and I could not get the nylon line to slide over the brass barbs, I had to use a blow torch, and quickly rotate the line while holding over the flame, and then I could finally get the line on the barbs of the fitting.
Of course I was inside working on the line, I'd have not tried that with a fuel line still on the car.
