REMOVAL
CAUTION: Cleanliness cannot be overemphasized when handling or replacing diesel fuel system components. This especially includes the fuel
injectors, high-pressure fuel lines and fuel injection pump. Very tight tolerances are used with these parts. Dirt contamination could cause
rapid part wear and possible plugging of fuel injector nozzle tip holes. This in turn could lead to possible engine misfire. Always wash/clean any
fuel system component thoroughly before disassembly and then air dry. Cap or cover any open part after disassembly. Before assembly,
examine each part for dirt, grease or other contaminants and clean if necessary. When installing new parts, lubricate them with clean engine oil
or clean diesel fuel only.
