Removal Procedure
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over disconnected fuel system component.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Dispose of all fluids according to local regulations and mandates.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Place identification marks on all hoses for installation purposes. Plug all hoses and all the ports in the fuel transfer pump. This helps prevent fluid loss, and this helps to keep contaminants from entering the system.
Turn the fuel supply to the OFF position.

Typical example
Note: The fuel transfer pump can be oriented in two positions. Before removing the fuel transfer pump from the cylinder block, note the orientation of flange (5) on fuel transfer pump (1) for assembly.
Loosen the hose clamps and disconnect the hoses (not shown) from fuel transfer pump (1).
Evenly loosen bolts (4) and remove fuel transfer pump (1) from the cylinder block. Note: In order to remove the fuel transfer pump, it may be necessary to rotate the crankshaft until the operating plunger of the fuel transfer pump is not under pressure.
Remove O-ring seal (3) from fuel transfer pump (1). Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 2 g01326306
Typical example
Clean the mating surfaces of the cylinder block and flange (5) on the fuel transfer pump. Note: Ensure that the camshaft lobe for the fuel transfer pump is at minimum lift before the fuel transfer pump is installed. The fuel transfer pump can be oriented in two positions. Ensure that the fuel transfer pump is oriented in the correct position.
Install a new O-ring seal (3) to fuel transfer pump (1).
Lubricate the operating plunger of fuel transfer pump (1) with clean engine oil.
Position fuel transfer pump (1) on the cylinder block. Ensure that the operating plunger is positioned correctly on the camshaft lobe. Install bolts (4). Tighten the bolts to a torque of 6 N m (53 lb in).
Connect the hoses (not shown) to fuel transfer pump (1). Tighten the hose clamps. Note: The inlet for the fuel transfer pump can be rotated 360 degrees by loosening bolt (2). The fuel inlet is adjustable in 15 degree increments. If adjustment is made to the position of the fuel inlet, tighten bolt (2) to a torque of 2.5 N m (22 lb in).
Turn the fuel supply to the ON position.
Prime the fuel system. Refer to Systems Operation, Testing and Adjusting, "Fuel System - Prime" for additional information.
