8. FUEL SYSTEM
(a) When disconnecting the high pressure fuel line, a large
amount of gasoline will spill out, so observe these proce-
dures:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped on
its own, turn the ignition switch OFF.
(3) Put a container under the connection.
(4) Slowly loosen the connection.
(5) Disconnect the connection.
(6) Plug the connection with a rubber plug.
(7) Reconnect the fuel pump connector.
(b) When connecting the flare nut or union bolt on the high
pressure pipe union, observe these procedures:
(1) Union Bolt Type:
Always use a new gasket.
(2) Union Bolt Type:
Tighten the union bolt by hand.
(3) Union Bolt Type:
Tighten the union bolt to the specified torque.
Torque: 29 N´m (300 kgf´cm, 22 ft´lbf)
(4) Flare Nut Type:
Apply a light coat of engine oil to the flare and tight-
en the flare nut by hand.
(5) Flare Nut Type:
Using SST, tighten the flare nut to the specified
torque.
SST 09631±22020
NOTICE:
Do not rotate the fuel pipe, when tightening the flare nut.
Torque:
30 N´m (310 kgf´cm, 22 ft´lbf) for using SST
38 N´m (387 kgf´cm, 28 ft´lbf)

INSPECTION
INSPECT FUEL TANK AND LINE
(a) Check the fuel lines for cracks or leakage, and all connec-
tions for deformation.
(b) Check the fuel tank vapor vent system hoses and connec-
tions for looseness, sharp bends or damage.
(c) Check the fuel tank for deformation, cracks, fuel leakage
or tank band looseness.
(d) Check the filler neck for damage or fuel leakage.
(e) Hose and pipe connections are as shown in the illustra-
tion.
If a problem is found, repair or replace the parts as necessary.

3. INSPECT FIELD COIL
(a) Check the field coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the lead wire and field coil brush lead.
If there is no continuity, replace the field frame.
(b) Check the field coil for ground.
Using an ohmmeter, check that there is no continuity be-
tween the field coil end and field frame.
If there is continuity, replace the field frame.
4. INSPECT BRUSHES
Using a vernier caliper, measure the brush length.
Standard length: 15.5 mm (0.610 in.)
Minimum length: 10.0 mm (0.394 in.)
If the length is less than minimum, replace the brush holder and
field frame.
5. INSPECT BRUSH SPRINGS
Check the brush spring load. Take the pull scale reading the
instant the brush spring separates from the brush.
Standard spring installed load:
17.6 ± 23.5 N (1.8 ± 2.4 kgf, 3.9 ± 5.3 lbf)
Minimum spring installed load:
11.8 N (1.2 kgf, 2.6 lbf)
If the installed load is less than minimum, replace the brush
springs.

NOTICE:
When using a vise, do not overtighten it.
1. CHECK OIL CLEARANCE BETWEEN VANE PUMP
SHAFT AND BUSHING
Using a micrometer and caliper gauge, measure the oil clear-
ance.
Standard clearance:
0.03 ± 0.05 mm (0.0012 ± 0.0020 in.)
Maximum clearance: 0.07 mm (0.0028 in.)
If it is more than the maximum, replace the shaft and front hous-
ing.
2. INSPECT VANE PUMP ROTOR AND VANE PLATES
(a) Using a micrometer, measure the height, thickness and
length of the 10 plates.
Minimum height: 8.6 mm (0.339 in.)
Minimum thickness: 1.40 mm (0.0551 in.)
Minimum length: 14.99 mm (0.5902 in.)
(b) Using a feeler gauge, measure the clearance between
the rotor groove and plate.
Maximum clearance: 0.033 mm (0.0013 in.)

3. INSPECT FLOW CONTROL VALVE
(a) Coat the valve with power steering fluid and check that it
falls smoothly into the valve hole by its own weight.
(b) Check the flow control valve for leakage.
Close one of the holes and apply compressed air
392±490 kPa (4±5 kgf/cm
2, 57±71 psi) into the opposite
side, and confirm that air does not come out from the end
holes.
If necessary, replace the valve with one having the same letter
as inscribed on the front housing.
