The rack must be in the center position to remove the fuel injection pump.
To prevent possible personal injury carefully follow the steps below.
2. Put Tooling (B) except for the 8T-5287 Wrench in position on the fuel pump housing as shown. Lower the handle to center the adjusting screw with the fuel line seat. With the handle down in the locked position, the adjusting screw must just be in contact with fuel line seat (1). If force is needed to lower the handle or there is a gap, remove the tooling, and make an adjustment to the screw.3. Loosen bushing (2) 1/4 of a turn.4. Put Tooling (B) in position on the pump housing with the handle down in the locked position as shown.5. Remove bushing (2) from the pump housing.6.

If there is no pump, take a pump already removed, and remove the spring so there will be no spring force, and install it in the pump housing. See Install Fuel Pump. Spacers (5) are the same thickness for each fuel injection pump so they can be mixed. The fuel injection pump plungers and barrels are sets and cannot be mixed.Install Fuel Injection Pumps
