Edelbrock Fuel Pump and Carburetor

as far as fuel filter media, the best I've found are old-school ceramic, or old-school sintered bronze filters. Whatever you go with, you need to drop the fuel tank, remove the sender/ pickup assy, and drop a couple of feet of hot dip galvanized 5/16" or 3/8" chain into the tank and a qt or two of an appropriate solvent, and litterally shake the crap out of it, until it's clean. Rinse, repeat.
Like I think I said before, use the inner cable of speedo cable to "snake" the steel fuel lines.
