Injector nuts
Note: If necessary, loosen the union nuts (1) on the
fuel injection lines at the connection with the fuel
injector until fuel is evident. Stop cranking the engine.
Tighten the union nuts to a torque of 27 N·m
(20 lb ft).
4. Start the engine and run the engine at idle for one
minute.
5. Cycle the throttle lever from the low idle position to
the high idle position three times. The cycle time
for the throttle lever is approximately one second
to six seconds for one complete cycle.
Note: In order to purge air from the fuel injection
pump on Perkins engines with a fixed throttle, the
engine should be run at full load for thirty seconds.
This should be repeated three times. This will assist
in removing trapped air from the fuel injection pump.
6. Return the engine to no load condition. Check for
leaks in the fuel system.
Fuel System Primary Filter/
Water Separator - Drain
Fuel leaked or spilled onto hot surfaces or electri-
cal components can cause a fire. To help prevent
possible injury, turn the start switch off when
changing fuel filters or water separator elements.
Clean up fuel spills immediately.
The water separator is not a filter. The water separa-
tor separates water from the fuel. The engine should
never be allowed to run with the water separator
more than half full. Engine damage may result.
The water separator is under suction during normal
engine operation. Ensure that the drain valve is tight-
ened securely to help prevent air from entering the
fuel system.

close the drain (5). Tighten the drain by hand
pressure only. Dispose of the drained fluid
correctly.
