(d) Check the valve overall length.
Standard overall length:
Intake98.4 mm (3.874 in.)
Exhaust97.4 mm (3.854 in.)
Minimum overall length:
Intake97.9 mm (3.854 in.)
Exhaust97.4 mm (3.835 in.)
If the overall length is less than minimum, replace the valve.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a grinder or
replace the valve.
NOTICE:
Do not grind off more than minimum.
7. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.
(b) Check the valve seating position. Apply a light coat of prussian blue (or white lead) to the
valve face. Lightly press the valve against the seat. Do not
rotate valve.
(c) Check the valve face and seat for the following:
If blue appears 360 ° around the face, the valve is
concentric. If not, replace the valve.
If blue appears 360 ° around the valve seat, the
guide and face are concentric. If not, resurface the
seat.
Check that the seat contact is in the middle of the
valve face with these width:
Intake1.2 − 1.6 mm (0.047 − 0.063 in.)
Exhaust1.0 − 1.4 mm (0.039 − 0.055 in.)

REMOVAL
CAUTION:
Do not smoke or work near an open flame when working on
the fuel pump.
1. REMOVE SECOND SEATS
Torque: 39 N·m (400 kgf·cm, 29 ft·lbf)
2. REMOVE SCUFF PLATE
3. REMOVE SIDE GARNISH
4. REMOVE STEP PLATE
5. DISCONNECT FLOOR MATS
6. REMOVE FLOOR SERVICE HOLE COVER

7. DISCONNECT FUEL PIPE AND HOSE FROM FUEL
PUMP BRACKET
CAUTION:
Remove the fuel filter cap to prevent the fuel from flowing
out.
(a) Disconnect the fuel pump and sender gauge connector.
HINT:
At the time of installation, plaese refer to the following items.
Check for fuel leakage.
(b) Remove the union bolt and gaskets, and disconnect the outlet pipe from the pump bracket.

INSPECTION
1. REMOVE SECOND SEATS
2. REMOVE SCUFF PLATE
3. REMOVE SIDE GARNISH
4. REMOVE STEP PLATE
5. DISCONNECT FLOOR MATS
6. REMOVE FLOOR SERVICE HOLE COVER
Remove the 3 screws and service hole cover.
7. DISCONNECT FUEL PUMP AND SENDER GAUGE CONNECTOR
8. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between the ter-
minals 5 and 6. Resistance: 0.2 − 3.0 Ω at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump.
9. INSPECT FUEL PUMP OPERATION
Connect the positive (+) lead from the battery to terminal 6 of
the connector, and the negative ( −) lead to terminal 5. Check
that the fuel pump operates.
NOTICE:
These tests must be performed quickly (within 10 se-
conds) to prevent the coil from burning out.
Keep the fuel pump as far away from the battery as
possible.
Always perform switching at the battery side.
If operation is not as specified, replace the fuel pump.
