Filling
A type of hand pump and primer plunger is located on the fuel filter bracket and is used to
• Refill the fuel filter when draining or changing the filter.
• Refill the fuel system on the engine if the system was run dry.
• Prime the fuel system if the engine has not been run for an extended period.
IMPORTANT: Only fill the fuel filter with the hand pump and primer plunger to ensure that unfiltered fuel does not get into the
fuel system.
NOTE: Follow this procedure after installing a new filter or if the fuel has been drained from the filter checking for water.
