You don't want to pull one of these out but that is the Fuel Injection Pump Element outer Barrel and the arrow points to the Fuel Feed Hole that might be plugged.

If it is a stuck plunger: would it work to put hydraulic pressure against the top of the plunger to push it down onto the cam and then hold it there while the cam is rotated enough to free it ? If so, what would the best fluid be ? ATF, MMO, Seafoam, diesel, B100
The advantage of this method (if it is viable and works) would be that you do not have to open up the pump and risk having things go horribly wrong.
