Oddly, four of the six splined collars (and the two torx screws that hold them in place) are missing on my 87 300TD. Only the collars for lines 5 and 6 are in place. So I'm looking at the EPC. Is the collar what MB calls the "shackle," part number 000 075 00 38? And is there a part number for the torx screw?

I definitely want to replaced these when I do the delivery valve seals. I assume their sole function is the increased rigidity of the line?

Thanks.

The Shackel is the stamped sheetmetal sort of teardroped shaped part with a splined hole; the inside diameter splined; designed to keep the Delivery Valve Holder on the Fuel Injection Pump from turning.

I have not read this but it is possible that the Clamps on the Fuel Injection Hard Lines are also called Shackels.
