2. Remove fuel filter, using a suitable tool.
3. Wipe clean fuel filter mounting surface on fuel filter bracket and
smear a little fuel on rubber seal of fuel filter.
4. Screw fuel filter on until a slight resistance is felt, then tighten
and additional more than 2/3 turn.
5. Install fuel filter sensor to new filter.
6. Bleed air from fuel line.
Refer to Bleeding Fuel System in EC section.
7. Start engine and check for leaks.
DRAINING WATER
1. Loosen drain cock and drain water.
Loosening drain cock 4 to 5 turns causes water to start drain-
ing. Do not remove drain cock by loosening it excessively.
If water does not drain properly, move the priming pump up and
down.
2. Bleed air.
Refer to section EC for fuel system bleeding instructions.

Checking Idle Speed
Preparation
1. Make sure that injection timing is correct.
2. Make sure that injection nozzle are in good condition.
3. Make sure that the following parts are in good condition.
IAir cleaner clogging
IGlow system
IEngine oil and coolant levels
IValve clearance
IAir intake system (Oil filler cap, oil level gauge, etc.)
4. Set shift lever in ªNeutralº position. Engage parking brake and
lock both front and rear wheels with wheel chocks.
5. Turn off air conditioner, lights and accessories.
IWarm up engine until water temperature indicator points to middle of gauge.
ILights, heater fan and all accessories are off.
IAttach tachometer's pick-up to No. 1 fuel injection tube.
In order to take accurate reading of engine rpm, remove clamps that secure No. 1 fuel injection tube.
Start engine.

4. Wipe clean fuel filter mounting surface on fuel filter bracket and
smear a little fuel on rubber seal of fuel filter.
5. Screw fuel filter on until a slight resistance is felt, then tighten
an additional more than 2/3 or a turn.
6. Install fuel filter sensor to new fuel filter. (Type A)
7. Bleed air from fuel filter.
Refer to ªAir Bleedingº in EC section.
8. Start engine and check for leaks.
DRAINING WATER
1. Drain water as follows.
Type A
Loosen drain cock and drain water.
Loosening drain cock four to five turns causes water to start
draining. Do not remove drain cock by loosening it exces-
sively.
If water does not drain properly, move the priming pump up and
down.
Type B
Loosen air bleeder screw from the sedimentor cover and then
loosen drain cock and drain water.
Loosening drain cock four to five turns causes water to start
draining. Do not remove drain cock by loosening it exces-
sively.
2. Bleed air.
Refer to ªAir Bleedingº in EC section.
Checking Fuel Lines
Check fuel lines and tank for proper attachment, leaks, cracks,
damage, loose connections, chafing and deterioration.
CAUTION:
Keep clean parts with compressed air when assembling.
