Good Afternoon Everyone, I need help in finding the right part for a ROTO Injection pump on our 2840, One of the Banjo Bolts or Hollow Screw? unsure of proper term, but this is the bolt/screw on the pump which fastens the fuel line from there to cylinder. One just popped off the other day, the head looked as if it cracked awhile ago, part of the fracture had rusted. The parts dept here gave me a part number R26726 HOLLOW SCREW, I looked it up online, it does not look anything like what broke. If you can please give me some guidance.
 

The screw that I see that attaches line to inj pump is AT29464 @ $55.49 from JD.

My GUESS is that they gave you the part number for the bolt for a Stanadyne Pump, you stated you have a Roto(diesel) injection pump.

If that is the case, the part number appears to be AT29464.

Roto-diesel bolt/valve.

You can look for yourself in the on-line parts lookup linked below.

Be SURE you have the correct part, there's a couple of diesel pump guys on here that will liekly chime in.

Using the wrong bolt will destroy your injection pump.
