  2. Set the holder to the fuel injector, and install it straight to the fuel injector pipe RH.
    CAUTION:
    • Always use a new holder.
    • Degrease inside of the fuel injector insertion hole of the fuel injector pipe.
    • Check the inside of the fuel injector insertion hole of the fuel injector pipe for foreign materials or damage.
    • Be careful not to allow gasoline to contact with the fuel injector seal and the inside of the mounting hole.
    • Apply liquid paraffin to the O-ring and install it.
    • Be careful not to twist the O-ring.
    • To prevent damage to the O-ring, insert the part straight along the fuel injector insertion axis without tilting it and avoid removing and inserting the part again.
    • To prevent the tip of the fuel injector from bending, do not apply force to the fuel injector tip.
    • Check that the tip of the fuel injector has no bend or damage.
    • Make sure there is no gap between the fuel injector pipe and the fuel injector holder.
