A New Fuel Transfer Pump and a New Check Valve Are Now Used on Certain C32 Marine Engines {1256, 1262}
- Generator Set:
- C32 MAR GS ENG (S/N: RNX1-UP)
- Marine Engine:
- C32 MARINE (S/N: RNY1-UP; RNZ1-UP)
Description of Change: In order to increase the fuel system pressure on the engines that are listed above, a new fuel transfer pump and a new check valve are now used. The change raises the fuel system pressure by approximately 172 kPa (25 psi).
Adaptable To: The new 327-4448 Check Valve Gp should not be applied to engines prior to the change, since the new check valve is not compatible with the old fuel transfer pump. The change to the new 327-4448 Check Valve Gp and the new 331-3635 Fuel Transfer Pump Gp is effective at the factory with serial numbers RNX00273-UP, RNY00686-UP and RNZ00290-UP.
