For the life of me, I cannot find where this leak is coming from. I got a mirror and light and have checked all around top where the injector housing connects to the straight rail. If there's a leak there, it is excellent at hiding. I can literally see gas slowly running down the injector. Somehow, at the exact same time, that little silver lip on the injector housing fills up with gas! I mean, I was under the impression that gas follows the laws of gravity. I cannot see gas running down the injector housing, yet gas pools up inside that lip. This is infuriating. It's hard to see what I need to replace if I can't find the source of the leak.
