I would remove the injector lines and try spraying a good penetrant in the outlet. There’s a discharge valve in there but maybe it leaks a little and your penetrant can soak into the piston.

Gentle tapping might get some back down but as mentioned earlier there’s always going to be one or two on the camshaft lobe, so gently is the rule. I personally would use a torch and heat the barrel of any that were uncooperative with the previous measures. The tolerances are so small that even a slight thermal expansion should help.

When working on trying to free up stuck pumps do not be tempted to apply rotational force to the sector gear on the plunger. This gear is simply clamped to the plunger and represents a precise calibration that is not easily done. Up and down tapping is okay .

ccjersey, Thank you so much, that's exactly what I needed! I suspect the torque on the 3/8 fine adjustment nut is around 35ftlbs. Vic

If you don't have a depth gauge micrometer, I did it with a dial indicating caliper.
