Rail, Fuel: Removal: 5.7L
WARNING:
The fuel system is under constant pressure even with engine off. Before servicing the fuel rail, fuel system pressure must be released.
CAUTION:
The left and right fuel rails are replaced as an assembly. Do not attempt to separate fuel rail halves at connector tube. Due to design of the connector tube, it does not use any clamps. Never attempt to install a clamping device of any kind to the connector tube. When removing fuel rail assembly for any reason, be careful not to bend or kink the connector tube.
