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.
The fuel pressure limiting valve (1) is screwed into the front of the fuel rail (2).
The fuel pressure limiting valve drain port is located on the side of the fuel rail next to the limiting valve. The drain port is not serviceable.
1. Thoroughly clean area at pressure limiting valve (1).
