I installed new injectors and pump a few weeks back and have discovered I have a leak coming from the head where the supply line threads in. The good part is that it is on the No 1 cylinder so it's easy to get to. I have tried to tighten it but it is in there firm. Looking for ideas here, hate the smell of diesel while I'm driving, makes me nervous.

I took mine to a Deisel shop in town just today. I have had the same problem with #5 after I had a (non deisel) mechanic bleed the air out of my fuel system. The diesel mechanic tried tightening the line twice but it kept leaking so then it was narrowed down to a damaged injector tube. Hope this helps you, Ive been going nuts trying to figure out my problem. It never had a miss but it did make it hard to start after it leaked down fuel pressure. Also my fiance kept complaining that I smelled like diesel all the time

Sounds like a messed up injector tube.
