NOTE: Before you work on the fuel lines and fittings,
read the Fuel Line/Quick-Connect Fitting Precautions
(see page 11-328).
1. Relieve the fuel pressure (see page 11-322).
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-connectfitting. 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
connector off.
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.

replacing the fuel rail.
replacing the fuel feed line.
replacing the fuel pump.
replacing the fuel filter.
replacing the fuel gauge sending unit.

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. Reconnect the negative cable to the battery, 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, then check that
there is no leakage in the fuel supply system.
