One filter is inside the mechanical fuel pump, the other filter is in the carburetor inlet. Unscrew the fuel line before unscrewing the big nuts on the pump outlet and carb inlet.

Be prepared for a lot of gasoline pouring down when you unscrew the big nut to extract filter in the pump. As refers to the carb. inlet filter, according to the shop manual, "as a further precaution against dirt in the carburetor, or fuel line a fuel inlet screen is provided behind the inlet nut of the carburetor. The fuel filter in the pump should be replaced each 12,000 miles or 12 months, preferably in the spring. The fuel inlet screen does not require periodic replacement but should be cleaned whenever the carburetor is overhauled. Also, it should be inspected when fuel flow problems are encountered".
