PRIMING FUEL SYSTEM

Priming the fuel system removes pockets of air in
the fuel lines and fuel components. Air in the fuel
system will prevent smooth engine operation.
Prime the fuel system after running out of fuel,
changing the fuel filter, disconnecting the low
pressure fuel lines, or any part of the low pressure
fuel system leaks during engine operation.
