Re: best fuel filter.
Engine needs only ten microns to run clean, anything smaller flows through the engine unnoticed. Recommended is a one hundred micron filter in the tank (the mesh strainer on the end of the pick up tube). I don't recommend paper filters because the alcohol in the fuel absorbs water and a wet paper filter isn't a good filter material for anything more than coffee.
Alcohol is here to stay so it is time to upgrade your car to burn it or consider driving around burning only racing gas that has to be kept in a closed container and burned five gallons at a time or it goes bad VERY quickly (anybody mention how expensive it is to buy then add the cost of shipping). So you need to consider a stainless steel gas tank as used on all new cars and trucks. Add to that stainless steel fuel lines three eighths of an inch in size or larger.
Assuming you are not overly concerned about restoration value you will also need an anodized aluminum Holley carburetor (in your choice of colors. Different companies sell a "Holley" looking carb in choices of red, green, black, and purple so far). The anodizing will protect the carburetor for a time, but the anodizing sacrifices itself to electrolysis from the reactants in the gas so it will be used up eventually. This is the true cost of gasohol that is added to older cars still on the road.
With an aftermarket electric fuel pump and a stainless steel, aluminum, or plastic fuel cell I would use a cleanable perforated stainless steel filter before the pump rated at one hundred microns and a stainless steel wool or a fiberglass fiber mesh ten micron filter after the pump and not worry about the one hundred micron sintered bronze strainer in the carb inlet. This will filter the fuel without adding additional fluid friction in the fuel delivery system.
