Avoid pensacola rebuilds. A buddy of mine bought a set of their injectors. 4 D codes 2 C codes a BB code, and a K code....... The nozzles on the D codes did not match, which tells me they just dump all of the nozzles and pintles together. He called them on it and they said that all they do is clean them. They said that their rebuilt pumps they "replace necessary parts" which in turn tells me that they are shoddily done.

On this note, I rebuilt my old injectors with a tester built from an hydraulic bottle jack. #4 stainless steel flat washers are the correct size for shims, I sanded them to smooth the edges and used them to adjust the pressure to 2300#
