I have a "minor" fuel leak... Sometimes when idling at a stop I get a very faint smell of gas... Looked under the hood today and noticed some wetness around the underside of this fitting to the fuel rail on top of the motor... It's the fitting on the side of the manifold closest to the firewall... I pushed the fitting up and down a little and then restarted the motor... I did not see any leakage... Rev'd the motor and still no leakage but it was definitely wet with a few drops of gas when I first popped the hood... How do I fix this?... Is there an O-Ring in the fitting?... How do you open or disconnect this fitting?... 2001 LS with 3.8L motor...

Pretty sure that's the return fuel line. Its a quick disconnect, push the two clear plastic tabs all the way on the bottom a.d pull up.

Push them in? Push them down? Still not sure how to remove this connector...

I'm looking for a replacement fuel line connector for this and so far all I see is a Dorman brand and it looks a little different than this...

Are they different sizes on the return and pressure side?

Squeeze the clear plastic tabs all the way on the bottom in and pull up. I don't know anything else sorry.

That's OK I know what you're saying... The aftermarket parts look like this and you squeeze the tabs in to release...

But my OEM connector looks different and seems to have a "U" shaped clip on the bottom which I think you push in and then pull up...

EDIT.....

OK, I see what you are saying now that I have better daylight...

There is a 2nd fuel connector on the opposite side of the manifold... I don't know which one is pressure and which one is return... But they fuel line diameter measures different for each... The one on the backside of the manifold measures 3/8" diameter and the one on the front side of the manifold measures 5/16" diameter...

But Dorman only sells a 3/8" fuel connector??

If you go to your local parts store, they usually sell the ends, just cut the old one off and put a new one on. Use the supplied clamp, heat it with a heat gun/hair dryer and your done.

I squeezed the tabs so that it partially disconnected and then reseated it until I heard it click... Leak seems to have stopped... No evidence of a gas drip and no more smell... Maybe it wasn't fully locked for some reason and I didn't know it...

They can be a little finicky... you never know, may have bumped it or it could have just been a freak chance that it worked a bit loose somehow.

the O rings failed on mine awhile back. there are 2 on the inside. its alot cheaper to fix. but if it's not leaking anymore then thats good.
