ELECTRIC STARTING MOTOR GROUP 2P6162 - Caterpillar

(4KG, 1SK) Marine EnginesDescription of Change: A fuel priming pump is available for installation on either left or right hand service fuel filters. The fuel priming pump can help remove air from the fuel system after filter changes or other fuel system maintenance. Adaptable To: The components of the 110-4394 Fuel Priming Pump Group are identified in Illustration 1 and Chart A.
Illustration 1. Location of components of the 110-4394 Fuel Priming Pump Group. See "LEFT HAND SERVICE" for the components required and the procedure to install a fuel priming pump on left hand service fuel filters. See "RIGHT HAND SERVICE" for the components required and the procedure to install a fuel priming pump on right hand service fuel filters.
Left Hand Service
New Components Require
Chart B and Illustration 2 identify the new components required to install the fuel priming pump on engines equipped with a left hand service fuel filter.
Installation Procedure
1. Remove the tube that connects the fuel transfer pump outlet to the fuel filter base inlet. Remove the fitting from the fuel filter base inlet.2. See Illustration 1. Remove pump assembly (3) from valve assembly (1). Use care not to loose ball (4) and spring (5).3. Install valve assembly (1) in the fuel filter base inlet. Assemble fuel priming pump group (9). Be sure ball (4) and spring (5) are in place before installing pump assembly (3) on valve assembly (1). Fuel priming pump group (9) should be oriented as shown in Illustration 2.4. Put new seals (7) in position on the fuel transfer pump outlet fitting and the new fuel priming pump group inlet.5. Install new tube assembly (8) between the fuel transfer pump outlet and the new fuel priming pump group inlet.6. See "Priming Procedure".

New Components Required
The 118-7266 Fuel Priming Pump Kit provides the components required to install a right hand service fuel priming pump if the engine was built with the 9Y-7694 Fuel Filter Group. Chart C and Illustrations 3 and 4 identify the components of the 118-7266 Fuel Priming Pump Kit. If the engine was built with the 110-4391 Fuel Filter Group, the only change required is to remove elbow (Z) and install the 110-4394 Fuel Priming Pump in its place.

Illustration 4. (Front View) Location of components in the 118-7266 Fuel Priming Pump Kit. The 110-4394 Fuel Priming Pump Group is not shown. Elbow (Z) is removed and the 110-4394 Fuel Priming Pump Group is installed where elbow (Z) was located.Installation Procedure
Illustrations 5 and 6 and Chart D identify the components to be removed from the 9Y-7694 Fuel Filter Group in order to install the 118-7266 Fuel Priming Pump Kit.
1. Remove the components identified in Chart D and Illustrations 5 and 6.2. Install new filter base assembly (20) as shown
