Fuel Pump - Cleaning and Inspection
for Reuse (05-01)
When removing the fuel pump from step timing control
(STC) engines, check to make sure the same Control
Parts List (CPL) number is on both the fuel pump dataplate
and the engine dataplate.
If the CPL number on the fuel pump dataplate does not
match the CPL number on the engine dataplate, the fuel
pump must be calibrated again to the correct specifica-
tion for the engine.
