FUEL INJECTION SYSTEM

NOTE:

CHECKING THE FUEL PUMP AND
PRESSURE REGULATOR OPERATION

1. Check:

pressure regulator operation

a. Remove the fuel tank.

Refer to “FUEL TANK” in chapter 3.

b. Disconnect the vacuum hose

from the

pressure regulator.

c. Connect the vacuum / pressure pump gauge

set

onto the vacuum hose from the pres-

sure regulator.

d. Connect the fuel pressure gauge

and

adapter

onto the fuel hose.

Vacuum / pressure pump gauge
set

90890-06756

Pressure gauge

90890-03153

Adapter

90890-03176

e. Install the fuel tank.

Refer to “FUEL TANK” in chapter 3.

f. Start the engine.
g. Measure the fuel pressure.

Fuel pressure

294 kPa (2.94 kgf/cm

, 2.94 bar)

h. Use the vacuum pressure pump gauge set to

adjust the fuel pressure in relation to the vac-
uum pressure as described below.

The vacuum pressure should not exceed 100
kPa (1 mmHg).

Increase the vacuum pressure

Fuel pressure is decreased

Decrease the vacuum pressure

Fuel pressure is increased

Faulty

Replace the pressure regulator.
