I think you said the delivery valve was cruddy. What do you think was in it?

I am asking that because if the rack is sticking whatever crud is inside of the pump can be the rack is sticking.

If the rack is not sticking crud could be restricting the fuel Feed Holes in the Element Barrels. Or the Plunger could have gone up and the crud is holding them up and the springs are not bringing them back down.
