Thanks for identifying that partial yellow ring Scott.
Interesting details!
I didn't really think it "played into" the cause of the OP's fuel leak
but thought I'd ask of it.

When checking injector spray pattern on my 2.1 WBX, sometime after I
replaced ALL the fuel hoses in engine bay, simply lifting the set of 2
injectors up and away from the driver side engine head caused a ***tiny***
bit of fuel to seep out between the fuel rail and hose. This was obviously
due to a slightly loose clamp.
(much like a radiator hose clamp replacement, I should have re-checked all
fuel hose clamps some miles after doing the fuel hose replacement job).
Tightening that fuel hose clamp fixed the issue. I re-checked all relevant
fuel hose clamps.

@ the OP. I may be mistaken, but I don't see that fuel pressure regulator
bolted down. Not that it matters per se, (as a fuel hose replacement job
may be in your near future), but I'd guess that simply moving that part,
and hoses attached to it, could have disrupted those old hoses and clamps
enough to cause a fuel leak ??

Neil.
