Started leaking diesel while driving. I could smell it, but coincidentally I had just filled a couple cans in the back of my 110 & thought the smell was from them. It wasn't until I stopped & noticed the trail of fuel behind me that I knew I had a problem. It only leaked when the engine was running & it leaked a lot - from a loose banjo bolt on the spill return rail to one of the injectors. Easy fix, just snug it up until it stops leaking. Then I Dumb-Assed it & snapped the head of the banjo bolt off. Fortunately I had a few old ones back home on a spare tdi engine. When I removed a couple (one for the fix & one for a spare to keep on the truck) I noticed the copper washers are thicker (or two have crushed together seamlessly). Have I been using the wrong copper washers since replacing my injectors? These banjo bolts have come loose before. I used the old thicker washers & tightened gently.
