• Lubricate the fuel line O-rings with a thin layer of engine oil (see fig. 6.37).
• Do not allow oil to enter the fuel line.
• Being careful not to damage the sealing ring, insert the fuel tube into the fuel line by turning it back and forth and make sure that the tube turns easily in its socket.
• If the tube turns in its socket with a jam, the sealing ring may be stuck.
• Remove the fuel pipe and check the condition of the sealing ring and, if damaged, replace it.
• Reinstall the fuel line and check that the line rotates easily in its seat.
• Install and tighten the fuel pipe flange mounting bolts to the specified torque.
