The rollers are hollow and when the break then pieces are just the perfect size to fit through the drain hole in the front of the pump. They then get picked up by the gear and thrown around which could be your crunch, there may also be damage inside the structure housing as theres not much clearance there.

Remove your fuel pump head and take a look at you rollers/pump cam.

All the gears are in excellent shape can’t find any chips or marks.

Pulled the head off the pump and found the roller furthest from the gear failed and the front one obviously junk with a crack across the face. So that one was not far from coming apart.
Your help was much appreciated!
