Fuel Leak - What’s this Hose?
Was backing down the driveway today when I noticed the smell of gas. Parked + popped the hood and noticed fuel dripping from this hose (see circled in red on photo). I moved around the hose clamps a bit and the leak stopped, but am not sure if it’ll come back.
What is this hose? Is it a regulator bleed off/return line? I couldn’t feel anything wrong with it. The only anomaly is that today was near 0F outside overnight before I started it. Not sure if that somehow contributed to the leak #shrinkage

Not sure if it's just me but the attachment isn't there.

Sorry about that...for some reason the photo wasn't uploading from my phone. Got it working on the computer. The hose in question is circled in red, just under/behind the heater core supply + return. The clamp on the right was moved in the photo as I was messing with it (in case you spot that it's off its imprinted position just to the right of its current spot in the photo).

Your attachments are -jpg and -png. That's not the correct format for files. They should be .jpg or .png
dot, no dash.

I'm not sure why it did that. When I preview the post, it'll show the image but then it doesn't show up when I submit the post. Trying again...it's showing as '.jpg' in the attachment list.

Well this is dumb... it shows up with the dot in my attachment list, but after I submit it, it changes the attachment to dash. I took a picture of it before submitting and verified that's what's happening.
In an attempt to describe the hose in question without the photo... it's on the driver's side, back top of the engine, immediately under the heater core supply+return hoses. The hose runs from the fuel rail there then by the master-cylinder/brake booster accumulator and connects to a hard tubing fuel connection.

Sounds like part # 2327350040 - HOSE, FUEL, NO.2
23273C in the diagram here:
I think it's a return line that comes off the passenger side fuel rail, running behind the intake manifold. Not cheap at around $150, depending where you buy it. But it's a fuel line and you DO want to replace it if it's leaking.
It's the hose with the white clip in this pic of my engine.

Yup, that's the hose! i thought it must be some type of return since it just had hose clamps and would've been at a lower pressure perhaps. The leak was at the connection of clamp 23273D (there's two of these clamps). Since 23273C is a hose, I'm hoping the leak point is it versus the metal tubing of 23803B. Buying a replacement. Thank you!!!
