Fig. 30 Fuel Rail Assembly - Typical V8
CAUTION: The left and right fuel rails are replaced as an assembly. Do not attempt to separate the rail halves at the connecting hose (Fig. 30). Due
to the design of this connecting hose, it does use any clamps. Never attempt to install a clamping device of any kind to the hose. When removing the
fuel rail assembly for any reason, be careful not to bend or kink the connecting hose.
REMOVAL
1. Remove negative battery cable at battery.
