(b) When connecting the union bolt on the high pressure pipe
union, observe these procedures:
(1) Always use 2 new gaskets.
(2) Tighten the union bolt by hand.
(3) Tighten the union bolt to the specified torque.
Torque: 29 N´m (300 kgf´cm, 21 ft´lbf)
(c) When connecting the flare nut on the high pressure pipe
union, observe these procedures:
(1) Apply a light coat of engine oil to the flare nut, and
tighten the flare nut by hand.
(2) Using SST, tighten the flare nut to specified torque.
SST 09631±22020
NOTICE:
Do not rotate the fuel pipe, when tightening the flare nut.
Torque: 28 N´m (285 kgf´cm, 21 ft´lbf) for using SST
HINT:
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
(d) Observe these precautions when removing and installing
the injectors.
(1) Never reuse the O±ring.
(2) When placing a new O±ring on the injector, take
care not to damage it in any way.
(3) Coat a new O±ring with spindle oil or gasoline be-
fore installing±never use engine, gear or brake oil.

Torque: 29 N´m (300 kgf´cm, 21 ft´lbf)
(e) Wipe off any splattered gasoline.
(f) Reconnect the negative (±) terminal cable to the battery.
(g) Connect a TOYOTA hand±held tester to the DLC3.
(See step 1 in check fuel pump operation (a) to (e))
(h) Measure the fuel pressure.
Fuel pressure:
301 ± 347 kPa (3.1 ± 3.5 kgf/cm
2, 44 ± 50 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the fuel hoses, fuel hose connections,
fuel pump, fuel filter and fuel pressure regulator.
(i) Disconnect the TOYOTA hand±held tester from the
DLC3.
(j) Start the engine.
(k) Measure the fuel pressure at idle.
Fuel pressure:
301 ± 347 kPa (3.1 ± 3.5 kgf/cm
2, 44 ± 50 psi)
(l) Stop the engine.
(m) Check that the fuel pressure remains as specified for 5
minutes after the engine has stopped.
Fuel pressure:
147 kPa (1.5 kgf/cm
2, 21 psi) or more
If pressure is not as specified, check the fuel pump, pressure
regulator and/or injectors.
(n) After checking fuel pressure, disconnect the negative (±)
terminal cable from the battery and carefully remove the
SST to prevent gasoline from splashing.
SST 09268±45014
(o) Reconnect the fuel inlet hose with 2 new gaskets and the
union bolt.
Torque: 29 N´m (300 kgf´cm, 21 ft´lbf)
(p) Reconnect the negative (±) terminal cable to the battery.
(q) Check for fuel leaks. (See page SF±1)

6. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between terminals
4 and 5.
Resistance: 0.2 ± 3.0 W at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump.
