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-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
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.
