In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 2% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
ACTION REQUIRED
Refer REHS3767, Special Instruction, "Inspection of Fuel Injection Pumps on 3054C, C3.3, C4.4 (Mech), and C7.1 (Mech) Engines", to determine if the failure of fuel pump is caused by dirty fuel or customer's maintenance practices, and record facts as specified. Apply this Service Letter program only if the inspection reveals FIP failure that is not attributable to customer's maintenance or use of contaminated / bad fuel.
Remove the existing fuel injection pump, and install a new 463-1678 Fuel Injection Pump Assembly.
Refer to UENR0674, Disassembly and Assembly, C7.1 (Mech) Engines, "Fuel Injection Pump Remove - With Boost Control", and install procedure, in order to complete this Rework Procedure.
