NOTE: Replace plastic fuel line retainers whenever the fuel supply or return line is disconnected at the fuel rail. Install the new retainer into the female cavity of the connection. Care must be taken to ensure that the locking tab is centered in the window of the female cavity. Firmly press the female connection onto the male end until a click is heard, then pull back to confirm engagement. Pinched, kinked, or damaged fuel lines must be replaced.

NOTE: Fuel/Vapor lines cannot be spliced or repaired. The line must be replaced (if damaged) with the same type of line.

Make sure lines are not kinked, bent, or damaged.
Install the fuel and vapor hoses. Make sure the lines are properly routed.
Attach the fuel line connectors at both ends. Connect the vapor line at both ends.
