FUEL SYSTEM (DFI) 3-115
Fuel Line

  Connect a commercially available vacuum/pressure
 pump [A] to the nipple of the delivery pipe [B] with the
 fuel hose [C] (both ends with the clamps [D]) as shown.
  Rear Side View [E]
○Apply  soap and water solution to the areas [F] as shown.
○Watching the pressure gauge, squeeze the pump lever
 [G], 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)

                          NOTICE
    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 fuel line is good.
 If the pressure drops at once or if bubbles are found in the
 area, the fuel line is leaking. Replace the delivery pipe
 assy, injectors and related parts.
○Repeat the leak test, and check the fuel line for no leak-
 age.
•Install:
   Fuel Hose (see Fuel Hose Replacement in the Periodic
   Maintenance chapter)
   Fuel Tank (see Fuel Tank Installation)
•Start the engine and check for fuel leakage.
