      NOTE:
      • Check around the connector for dirt or mud before this operation. Remove the dirt if necessary.
      • Be careful of mud because the fuel tube joint has an O-ring which seals the pipe and connector that can be contaminated.
      • Do not use any tools in this operation.
      • Do not bend or twist the nylon tube. Protect the connector by covering it with a vinyl or plastic bag.
      • When the pipe and connector are stuck, push and pull the connector to release. Pull the connector carefully.
