Check the fuel level in the fuel tank. Ensure that the vent in the fuel cap is not filled with dirt.
Check all fuel lines for fuel leakage. The fuel lines must be free from restrictions and faulty bends. Verify that the fuel return line is not collapsed.
Install a new fuel filter.
Cut the old filter open with the 4C-5084 Oil Filter Cutter. Inspect the filter for excess contamination. Determine the source of the contamination. Make the necessary repairs.
Service the primary fuel filter (if equipped).
Operate the hand priming pump (if equipped). If excessive resistance is felt, inspect the fuel pressure regulating valve. If uneven resistance is felt, test for air in the fuel. Refer to Testing and Adjusting, "Air in Fuel - Test" for more information.
Remove any air that may be in the fuel system. Refer to Testing and Adjusting, "Fuel System - Prime".
