I have what I think is an injector leak. Three of them - dry as a bone. The fourth (first from the left as I face the engine) looks like this:
The fuel seems to be leaking out near where the metal pipe attaches. From other related threads I've looked into, it seems there's some hope that tightening, or unscrewing and rethreading, the nut might get things back in proper order. Any suggestions or ideas as to what might be causing this and what I can do to fix it are more than welcome.
Full disclosure: I recently switched from a 20% biodiesel blend (dipping to about 10% due to a top-off with regular diesel in the dead of winter) to 100% biodiesel. I don't know for certain whether the timing is close between the switch and the leak, as I didn't notice the leak until small amount of fuel ended up on my driveway (about 1-2 inch spots, a half dozen or so). I'm also not clear on how or why it might be connected, but didn't want to leave out anything. And yes, the engine cover is now going to take up semi-permanent residency in the garage.
