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:

Caution
l Be sure the battery connections are not reversed, because this will damage the rectifier.
l Do not use high-voltage testers such as a megger, because they will damage the rectifier.
l Remember that battery voltage is always applied to the alternator B terminal.
l Do not ground the L terminal while the engine is running.
l Do not start the engine while the connector is disconnected from the L and S terminals.
1. Remove in the order shown in the figure.
2. Inspect all parts and repair or replace as necessary
