Found an extremely small dot of fluid under my truck one morning. I kept an eye on it and it didn't look bad. The fluid, which turns out to be diesel fuel, was dripping down a harness thats routed under the injection pump. I can't see all the way around the pump but the harness is dry above the pump and halfway down the pump. The leak produces 1 drop every couple of minutes when the engine is running at 1500 RPM. Has anyone had any experience with this kind of thing.
