INSTALLATION
1. TEMPORARILY INSTALL INJECTORS AND
DELIVERY PIPES
(a) Install 2 new grommets to each injector.
(b) Apply a light coat of spindle oil or gasoline to 2 new O−
rings and install them to each injector.
(c) While turning the injector clockwise and counterclock-
wise, push it to the delivery pipes. Install the 6 injectors.
(d) Position the injector connector outward.
(e) Place the 4 spacers in position on the intake manifold.
(f) Place the delivery pipes with the 6 injectors in position on
the intake manifold.
(g) Temporarily install the 4 bolts holding the delivery pipes
to the intake manifold.
(h) Check that the injectors rotate smoothly.
HINT:
If injectors do not rotate smoothly, the probable cause is incor-
rect installation of O−rings. Replace the O−rings.
(i) Position the injector connector outward.
2. CONNECT INJECTOR CONNECTORS
3. INSTALL FUEL PIPE AND TIGHTENING
DELIVERY PIPE HOLDING BOLTS
(a) Install the fuel pipe with 4 new gaskets and the 2 union
bolts.
Torque: 34.3 N·m (350 kgf·cm, 25 ft·lbf)
(b) Tighten the 4 bolts holding the delivery pipes to the intake
manifold.
Torque: 13 N·m (130 kgf·cm, 10 ft·lbf)

4. CONNECT FUEL INLET PIPE
(a) Temporarily install the union and 2 new gaskets, and con-
nect the fuel pipe.
(b) Install the clamp bolt.
Torque: 8 N·m (80 kgf·cm, 71 in.·lbf)
(c) Tighten the union bolt.
Torque: 34.3 N·m (350 kgf·cm, 25 ft·lbf)
5. INSTALL FUEL PRESSURE REGULATOR
(See page SF−17)
6. VISUALLY INSPECT AIR ASSIST LINES AND
CONNECTIONS
Look for loose connections, sharp bends or damage.
7. INSTALL INTAKE AIR CONNECTOR
(See page EM−69)
8. INSTALL AIR CLEANER HOSE
9. CHECK FOR FUEL LEAKS

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.

INSPECTION
1. INSPECT MAF METER RESISTANCE
Using an ohmmeter, measure the resistance between terminals
THA and E2.
Between
terminalsResistanceTemperature
THA − E210 − 20 kΩ−20°C (−4°F)
THA − E24 − 7 kΩ0°C (32°F)
THA − E22 − 3 kΩ20°C (68°F)
THA − E20.9 − 1.3 kΩ40°C (104°F)
THA − E20.4 − 0.7 kΩ60°C (140°F)
THA − E20.2 − 0.4 kΩ80°C (176°F)
If the resistance is not as specified, replace the MAF meter.
2. INSPECT MAF METER OPERATION
(a) Connect the MAF meter connector.
(b) Using a voltmeter, connect the positive (+) tester probe to
terminal VG, and negative (−) tester probe to terminal E3.
(c) Blow air into the MAF meter, and check that the voltage
fluctuates.
If operation is not as specified, replace the MAF meter.
(d) Disconnect the MAF meter connector.
