Checking the fuel pump

1.

Install the special service tool onto the
fuel pump as shown.

2.

Apply the specified pressure to each fuel
pump port. 

3.

If air flow is reversed, check the dia-
phragm for tears and the valves for
cracks. Replace if necessary.

CAUTION:

Do not over pressurize the fuel pump, oth-
erwise excessive pressure may cause air
leakage.

NOTE:

• Make sure that air does not escape from

the opposite side of the fuel pump.

• To eliminate any gaps between the fuel

pump valves and the fuel pump body 2, and
to ensure a better seal, make sure that the
inside of the fuel pump is moist with gaso-
line.
