I recall when I did this I simply took the injectors to a diesel shop and
they rebuilt them. You can't compete with them. They have jigs that simulate
the engine operation on a bench while measuring the pop and pattern.
If they need to be rebuilt do all 4 at once. They put these Bosch inserts
inside them. I forget how much it did cost. Maybe 150$ for all and the pump
was 400$.
