Got a 410D, little perkapillar with a fuel leak looks like by the fuel pump. Cleaned everything and will go back tomorrow to see where it's wet at. Thought I would see if anyone has ran into these pumps leaking and or part of it leaking? Machine has 5,7xx hours with a BFP prefix.
420D CAT? or ?? If you're talking about a lift/transfer pump then just about any part of them can leak. The diaphragm can leak and there's "usually?" a weep hole so the fuel doesn't find it's way into the oil. Or it can leak out the side, if there's a circle of screws you can try tightening them up a bit.
416d sorry. Did the the post from my phone so can't see full text before I send. Driving to machine now (little over an hour to Reno). If the boys haven't ran it I will and check my towels to see where fuel is leaking from. Looked to me like a very slow seep but we will see today. Have to do hydraulic clean out on vibromax front drum roller there too today. It looked to be concentrated around throttle linkage but could be wrong.
