pressure regulator and/or injector.
(s) After checking fuel pressure, disconnect the battery
negative (±) cable and carefully remove the SST to
prevent gasoline from splashing.
SST 09268±45012
(t) Connect the fuel inlet hose with 2 new gaskets and
the union bolt.
Torque: 29 N±m (300 kgf±cm. 22 ft±lbf)
(u) Reconnect the cable to the negative (±) terminal of
the battery.
(v) Check for fuel leakage.(o) Reconnect the vacuum sensing hose to the air intake
chamber.
(p) Measure the fuel pressure at idle.
Fuel pressure:
206 ± 255 kPa (2.1 ± 2.6 kgf/cm
, 31 ± 37 psi)
If pressure is not as specified, check the vacuum
sensing hose and fuel pressure regulator.(l) Start the engine.
(m) Disconnect the vacuum sensing hose from the air
intake chamber and plug the air intake chamber
outlet.
(n) Measure the fuel pressure at idle.
Fuel pressure:
265 ± 304 kPa (2.7 ± 3.1 kgf/cm
, 38 ± 44 psi) (k) Remove the SST.
