See TM 9-2320-272-24P-1 figure 96. Cummins OEM part number on page 96-1. (146483) This is for the M936 wrecker which has a VS (variable speed) fuel pump versus the AFC fuel pump installed on other NHC 250 engines which is figure 95 and same part number on page 95-1. The VS fuel pump is needed for the hydraulic operations of the wrecker crane.
I have not looked at my pump yet to verify it. I will tonight. The VS fuel pump filter screen is located on the bottom like others on this site have mentioned. It does NOT have a slotted access port. It is held in place by a split ring retainer.
I hope this helps my engine run better. I am expecting to see it plugged up with diesel fuel biological slime stuff like I found in the fuel filter.
I will post my findings tomorrow. I hope this helps someone.
