You have an M type fuel injection pump. It is the MW fuel injection Pumps that the fuel is adjusted from outside of the Fuel Injection Pump.
The fuel adjustments on your M type pump for the individual elements is done under that sheet metal cover on the side of the Pump. Stay away from those Adjustments.
The caution when changing the delivery valve holder O-ring and the copper crush washer on the M type fuel injection pumps is that a few people have managed when pulling the delivery valve to pull up the element barrel/body up and out of the alignment slot.
In the attached pic on the bottom part you can see the aliment slot. There is a pin in the Fuel Injection Pump housing that goes into that slot. You don't that element barrel to be pulled up.
When you do the work change only one seal at a time. When you assemble it screw in the delivery valve holder with the splined socket till it bottoms out only a little tight and then compare how high it sits to the rest of the delivery valve holders. If a element barrel has come up and out and is no longer lined up the Delivery Valve Holder will be obviously higher then the rest of them. If it is obviously higher don't torque it.
