Installation Procedure

WARNING: This page is about a different car, the 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
    CAUTION: In order to reduce the risk of fire and personal injury, before connecting fuel pipe fittings, always apply a few drops of clean engine oil to the male pipe ends.
    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.
