Most diesel engines can be filled with either running the electric lift pump, or if they're manual they usually have a lever to manually pump the filters full, and bleed the system. As sensitive as injection systems are to dirt, I would imagine they want the fluid sent to the filter, and filtered through it, same as if it were running. I never fill them when servicing a machine or my trucks, always pump it through the filters.
