NOTE:

New High Pressure Fuel Line must be used any time the High Pressure Fuel 
Lines have been removed.

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.
