Duetz F2L511 fuel leak at injector pump

[ToxicTrav117]

On our old Wacker Neuson R1000, we have a leak at the base of the nuts on top of the injector pump where the lines thread in. Is there some kind of washer or O ring that goes on the bottom of this? I can't find any mention of the parts online so I'm wondering if anyone else has had this problem and has a part number or something.

Looks like a Bryce pump. Under the nut is an o-ring, according to the parts diagram. Lots of parts kits on EBay. You could probably match up the old ‘o’ring with a new viton one.

That picture ain't exactly our machine because I have to clean ours off first but the pump still looks the same. So you think a o ring would solve the problem?

Yes. Be detail oriented. Don’t mess up the index of the P&B assembly. Keep it clean. It will be easier to assemble if the pump camshaft is on the base circle and not pushing up on the P&B.

Oring & probably a delivery valve gasket (copper)
The leak may be something as simple as RE-torquing to 35 ftlbs..

The o ring had some cracks in it. Replaced it and we are all fixed. Thank you to everyone for insight!

Now that you know how to do it you might as well do the other delivery valve o-ring, 'cause you know it's going to start leaking next week.
