CAUTION:
The left and right fuel rails are replaced as an assembly. Do not attempt to separate the fuel rail halves at the connector tube. Due to the 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 the fuel rail assembly for any reason, be careful not to bend or kink the connector tube.
