Fuel Line/Quick-Connect Fitting Installation

NOTE: Before you work on the fuel lines and fittings, read the "Fuel Line/Quick-Connect Fitting Precautions" (see FUEL LINE/QUICK-CONNECT FITTING PRECAUTIONS ).
  1. Check the contact area (A) of the line (B) for dirt or damage, and clean it if needed.

  2. Insert a new retainer (A) into the connector (B) if the retainer is damaged, or after:
    • replacing the fuel rail.
    • replacing the fuel line.
    • replacing the fuel pump.
    • replacing the fuel filter.
    • replacing the fuel pressure regulator.
    • replacing the fuel gauge sending unit.
    • replacing the EVAP canister.
    • replacing the fuel fill pipe.
    • replacing the fuel tank.
    • removing the retainer from the line.
    • Use the same manufacturer retainer and the same size retainer when the replacing the retainer (see FUEL LINE/QUICK-CONNECT FITTING PRECAUTIONS ).

  4. Align the quick-connect fittings with the line (A), and align the retainer locking tabs (B) with the connector grooves (C). Then press the quick-connect fittings onto the line until both retainer tabs lock with a clicking sound.
    NOTE: If it is hard to connect, put a small amount of new engine oil on the line end.

  5. When you reconnect the connector with the old retainer, make sure the connection is secure and the tabs (A) are firmly locked into place; check visually and also by pulling the connector (B). When you replace the fuel line with a new one, make sure you remove the ring pull (C) upwards after you confirm the connection is secure.
    NOTE: Before you remove the ring pull, make sure the fuel line connection is secure. If the connection is not secure, the ring pull could break when you try to remove it.

  6. Do the battery terminal reconnection procedure (see BATTERY TERMINAL DISCONNECTION AND RECONNECTION ), and turn the ignition switch to ON (II) (but do not operate the starter motor). The fuel pump will run for about 2 seconds, and fuel pressure will rise. Repeat this two or three times, and check that there is no leakage in the fuel supply system.
  7. If equipped, install the quick-connect fitting cover. Set the groove of the cover (A) on the fuel line (B) as shown, then install it. Make sure the cover is firmly locked in place.
