I am not sure if this is the right forum for this Lincoln question but here we go. I own a 1965 Lincoln that has 65,000 miles on it and its original 430 4brl engine. It starts right up if I spray carb. cleaner down the carburetor. Otherwise the carb. isn't getting fuel from the tank. I know this because I have glass in-line fuel filter positioned before the fuel pump to keep any potential crud from the gas tank from reaching the carburetor. Only a small amount of fuel is reaching the glass filter. Does this mean my fuel pump has gone out or could it be my fuel line is blocked by crud from the tank? Any thoughts? Thanks in advance!
