3-86 FUEL SYSTEM (DFI)

Fuel Injectors

•

Check the injector fuel line for leakage as follows:

○

Connect a commercially available vacuum/pressure

pump [A

] to the nipple of the delivery pipe [B] with a

high-pressure fuel hose [C] (both ends connected with

the clamps [D]) as shown.

Torque - Fuel Hose Clamp Screws: 1 .5 N·m (0.15 kgf·m, 13

in·lb)

○

Apply soap and water solution to the areas [E] as shown.

○

Watching the pressure gauge, squeeze the pump lever

[F], and build up the pressure until the pressure reaches

the maximum pressure.

Injector Fuel Line Maximum Pressure

Standard: 300 kPa (3.06 kgf/cm², 43 psi)

CAUTION

During pressure testing, do not exceed the maxi-

mum pressure for which the system is designed.

•

Watch the gauge for at least 6 seconds.

If the pressure holds steady, the system is good.

If the pressure drops at once or i f bubbles are found in

the area, the line is leaking. Replace the delivery pipe,

injectors and related parts.

○

Repeat the leak test, and check the fuel line for no leak-

age.

•

Install the pump outlet hose (see Fuel Tank Installation).

•

Run the hoses correctly (see Cable, Wire, and Hose Rout-

ing section in Appendix chapter).
