The fuel line/quick-connect fittings (A), (B), (C), (D)
connect the fuel rail (E) to the fuel feed hose (F), the fuel
feed hose to the fuel line (G), the fuel line (H) to the fuel
tank unit (I) and the fuel vapor line (J) to the EVAP
canister (K). When removing or installing the fuel feed
hose, fuel tank unit, or fuel tank, it is necessary to
disconnect or connect the quick-connect fittings.
Pay attention to the following:

• The fuel feed hoses, fuel line, and quick-connect

fittings are not heat-resistant; be careful not to
damage them during welding or other heat-
generating procedures.

• The fuel feed hoses, fuel line, and quick-connect

fittings are not acid-proof; do not touch them with a
shop towel that was used for wiping battery
electrolyte. Replace them if they come in contact with
electrolyte or something similar.

• When connecting or disconnecting the fuel feed

hoses, fuel line, and quick-connect fittings, be careful
not to bend or twist them excessively. Replace them
if they are damaged.

A disconnected quick-connect fitting can be
reconnected, but the retainer on the mating line cannot
be reused once it has been removed from the line.
Replace the retainer when:

• replacing the fuel rail.
• replacing the fuel line.
• replacing the fuel pump.
• replacing the fuel filter.
• replacing the fuel gauge sending unit.
• replacing the EVAP purge line.
• replacing the EVAP canister.
• it has been removed from the line.
• it is damaged.

read the ‘‘Fuel Line/Quick-Connect Fitting Precautions’’
(see page 11-292).

1. Relieve the fuel pressure (see page 11-286).

2. Check the fuel quick-connect fittings (A) for dirt,

and clean them if needed.

3. Place a rag or shop towel over the quick-connect

fitting. Hold the connector (A) with one hand, and
squeeze the retainer tabs (B) with the other hand to
release them from the locking tabs (C). Pull the

NOTE:

• Be careful not to damage the line (D) or other

parts. Do not use tools.

• If the connector does not move, keep the retainer

tabs pressed down, and alternately pull and push
the connector until it comes off easily.

• Do not remove the retainer from the line; once

removed, the retainer must be replaced with a
new one.

4. Check the contact area (A) of the line (B) for dirt or

damage.
