Cozmo, I'm on the fence about the AN stuff. As said its nice and easy to R&I once its all made up, but I've got some seepage issues on the ones for my oil cooelr as well...just aggrivating. But i'll address them slowly.
The line thats leaking may be leaking as you say, and working its way up the SS sheath, but I ahve a feeling the line just has a hole in it. It literally sprays a stream across the TB, onto the top of the engine, and up a bit onto the hood

I turned the pump on at first and could smell gas bad, I poked my head out of the cabin and went HOLY MOTHER!
Really no idea how that happened, they were all fine before. I have a piece of -6 that might be long enough to replace it, if not I'll use some regular old 3/8" fuel injector hose and nasty clamps to get me by for now.
I love the ease of AN, but its a bit of a pain in the rear to make. I'm already cringing at the number of pinholes im going to make in my hands fixing this one

If I did it again I'd use the black nylon sheathed stuff....wouldn't abriad anything touching it as badly I'd think.
