SFI INJECTOR
1996 LAND CRUISER (RM451U)
INSTALLATION
1. INSTALL INJECTORS AND DELIVERY PIPE
(a) Install a new grommet to the injector.
(b) Apply a light coat of gasoline to a new O −ring and install
it to the injector.
(c) While turning the injector left and right, install it to the de-
livery pipe. Install the 6 injectors.
(d) Position the injector connector upward.
(e) Place 6 new insulators and the 3 spacers in position on the intake manifold.
(f) Place the 6 injectors together with the delivery pipe in position on the intake manifold.
(g) Temporarily install the 3 bolts holding the delivery pipe 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 upward.
(j) Tighten the 3 bolts holding the delivery pipe to the intake manifold.
Torque: 21 N·m (210 kgf·cm, 15 ft·lbf)

SFI FUEL TANK AND LINE
SF−37
1996 LAND CRUISER (RM451U)
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 tube connections are as shown in the illustra- tion.
If a problem is found, repair or replace the part as necessary.

SFI MASS AIR FLOW (MAF) METER
1996 LAND CRUISER (RM451U)
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.
