Intake Manifold (Upper) Installation (4.3L, 5.0L & 5.7L)
CAUTION:
Always apply a few drops of clean engine oil to the male fuel pipe ends before connecting fuel pipe fittings in order to reduce the risk of fire and personal injury. This will ensure and prevent a possible fuel leak. During normal operation, the O rings located in the female connector will swell and may prevent proper reconnecting if not lubricated.
NOTE:
Manufacturer does not provide a torque sequence for upper intake manifold on 4.3L, 5.0L & 5.7L engines.
