Sierra 1500 4WD V6-4.3L (2008)
Caution: Always apply a few drops of clean engine oil to the male pipe ends before connecting the fuel pipe fittings in order to reduce the risk
of fire and personal injury. This will ensure proper reconnection and prevent a possible fuel leak. During normal operation, the O-rings located
in the female connector will swell and may prevent proper reconnection if not lubricated.
1. Apply a few drops of clean engine oil to the male pipe end.
2. Push both sides of the fuel line connections together in order to snap the retaining tabs into place.
3. Once installed, pull on both sides of the fuel line connections to ensure that the connection is secure.
