PRESSURE REGULATOR
Inspection
Fuel line pressure
Warning
l Before performing the following operation, release
the fuel pressure from the fuel system to reduce the
possibility of injury or fire. (Refer to page F-121.)
1, Disconnect the negative battery terminal.
2. Connect a fuel pressure gauge between the fuel filter and
the fuel main hose. (Install clamps as shown.)
3. Connect the negative battery terminal.
4. Start the engine and run it at idle.
5. Measure the fuel line pressure.
Fuel line pressure:
206-255 kPa (2.1-2.6 kg/cm2, 30-37 psi)
6. Disconnect the vacuum hose from the pressure regulator
and measure the fuel line pressure.
Fuel line pressure:
265-314 kPa (2.7-3.2 kg/cm2, 36-46 psi)

More than 147 kPa (1.5 kg/cm2, 21 psi)
9. If not as specified, replace the pressure regulator.
Replacement
Warning
l Before performing the followlng operation, release
the fuel pressure from the fuel system to reduce the
possibility of injury or flre. (Refer to page F-l 21.)
l When replacing fuel system components, keep
sparks, cigarettes, and open flames away from the
fuel.
1. Disconnect the vacuum hose.
2. Disconnect the fuel return hose.
3. Remove the pressure regulator.
Tightening torque:
7.8-11 N#m (80-110 cm-kg, 89-95 In-lb)

SOLENOID VALVE (PRESSURE REGULATOR CONTROL)
Inspection
On-vehicle
1. Start the engine and run it at idle.
2. Disconnect the vacuum hose (Orange) from the pressure
regulator. Verify that vacuum is felt.
3. Ground the solenoid valve terminal-wire G/O with a jumper
wire. Verify that no vacuum is felt.
4. If vacuum exists, check the solenoid valve.
Solenoid Valve
1. Disconnect the vacuum hose from the solenoid valve and
vacuum pipe.
2. Blow through the solenoid valve from port @
3. Verify that air flows from port @.
4. Disconnect the solenoid valve connector.
5. Connect battery voltage and a ground to the terminals of
the solenoid valve.
6. Blow through the solenoid valve from the port @.
7. Verify that air flows from the valve air filter.
8. If not as specified, replace the solenoid valve.
