a comment.....
Just order a new part from Audi. That is a fire waiting to happen. Leaks of that type were prevalent back in the day on 944's and 944 turbos. The fix from Porsche was a warranteed hose and to upgrade to turbo motor mounts. You might check your drivetrain mounts. Those types of fittings don't like very much movement, if at all. You might consider while in there, replacing the upper and lower injector seal o-rings, as you've done a fair bit of the work already.

"fire waiting to happen"...yeah, tell me about it, I smell a little gas, look under the hood...
and it's dripping onto the nice hot passenger side valve cover and evaporating instantaneously. I'm going to leave it parked until I get it fixed. I just wish it wasn't so damn cold (-5F when I had to bike to school today)

"wish it wasn't so damned cold''...
I hear you, its pretty crisp here as well and I've got numerous projects sitting on the burner. Use a pair of nitrle gloves while working, its a modest help. Nice pic.

This is an old, old, old problem for which the solution has been worked out for
all of the earlier platforms that had similar problems. Take the time to run through the C4, S-Car, 4000, 100/200/5000/V8 boards some time and see for yourself.
Audi even did a recall for certain years of the 100/A6 for this exact problem.
3 options exist for the repair:
- Buy a whole new part and install after you sh*t yourself from sticker shock.
- Remove the whole part and have it rebuilt by any of the run-of-the-mill hydraulic hose rebuilders that are in every big and small town. I've had it done for around $20 while I wait.
- Splice in a foot or so of suitable fuel injection line with high-quality clamps. This will take you 20 minutes and under $5 in parts.
- A 4th option using epoxy is shown on Audipages.com, but I personally wouldn't drive a car rigged like that.
VW uses the 'hose with clamps' setup on many of its motors instead of the crimped connection that's the subject of this thread. It's a viable and cheap solution.

I'm not sure how that would work with my line. The 30v appears to be different.

not really

fwiw, use the 2nd method shown on this page. The first method using epoxy seems quite dodgy to me.<ul><li><a href="http://www.audipages.com/Tech_Articles/enginemechanical/fuelleakrepari.html">http://www.audipages.com/Tech_Articles/enginemechanical/fuelleakrepari.html</a</li></ul>
