it's a very simple job to unbolt and remove the head from the pump to inspect it every year or maybe 100,000 miles. Work it in with other period maintenance, like an overhead adjustment, battery cable cleaning, EGR tuneup (if functional), etc...

I don't know about this.... every time you open that pump you're introducing contamination no matter how careful you are, you're also potentially shortening the pumps life or other components in the fuel system. The fuel filter on the block is a 4 micron, that means anything bigger than that is to big to be in there!! Obviously it must be rebuilt at 400k to prevent catastrophe but I think opening it up regularly is a mistake, just my opinion.
