Fuel Injection Pump
FUEL INJECTION PUMP
Removal of Fuel Injection Pump
1. Loosen the cooling fan V-belt.
2. Remove the engine coolant fan guard (if
equipped), engine coolant fan (Figure 7-8, (2)),
spacer (Figure 7-8, (3)) if equipped, V-pulley
(Figure 7-8, (4)) and cooling fan V-belt
(Figure 7-8, (1)).
Figure 7-8
3. Close any fuel valves in the fuel supply line.
4. Place a drain pan under the fuel injection pump
to catch any spillage.
5. Remove the high-pressure fuel injection lines
as an assembly (Figure 7-9, (1)).
Note: To prevent “rounding” the fuel line nuts
always use a “line” or “flare nut” wrench.
When loosening the fuel line nuts,
always hold the fuel injection pump
delivery valves with a “back up” wrench
to prevent loosening of the delivery
valves.
6. First loosen the fuel line nuts at the fuel
injectors and then at the fuel injection pump.
7. Finish loosening all the fuel line nuts and
remove the high-pressure fuel lines as an
assembly being careful not to bend any of the
fuel lines. Be sure to protect the fuel system
from contamination by covering all open
connections.
8. Disconnect the coolant lines from the cold start
device (Figure 7-9, (3)) on the fuel injection
pump. Plug the open ends of the lines to
minimize leakage and prevent contamination.
This cooling water pipe is not used in
electronically controlled engines 4ÇsNV84T-Z,
4TNV98-Z, 4TNV98-Z, and 4TNV98T-Z.
9. Disconnect the fuel return lines from the fuel
return fitting (Figure 7-9, (2)). Plug the open
ends of the lines to minimize leakage and
prevent contamination.

CAUTION
Remove or install the high-pressure fuel
injection lines as an assembly whenever
possible. Disassembling the
high-pressure fuel injection lines from
the retainers or bending any of the fuel
lines will make it difficult to reinstall the
fuel lines.
