The water is removed by loosening the screw (item
1)
[A]
at the bottom of the fuel filter. Tighten the screw after the
water has been removed.
Fuel Lift
Pump
Repair kits are available for the lift pump. Check the lift
pump pressure by turning the engine over and checking
with a gauge.
If the pump does not give enough pressure,
install the repair kit or replace the pump. (See Section 8
for the correct pressure.)
Fuel
Injection
Pump
To
check delivery valves and pump elements
do
the
following:
Remove the fuel injection lines from the injection pump.
Install the pressure indicator tool loosely to one of the
open connections [B]. Turn the engine over several
revolutions to remove air and ten tighten the nut.
Open the throttle.
Turn the engine with the starter until the pressure on the
gauges is at least
1074 PSI (7909 kPa). Wait for one
minute. The decrease in pressure must not be more than
145
PSI
(100 kPa) on the delivery valve.
Turn the engine five revolutions. The pressure shown on
the gauge must be at least 4347
PSI (300 bar).
If either of the two pressures are low the pump is
damaged.
