my 71 I've put two fuel filters on it due to having some junk in the tank. I took it out and cleaned it out best I could at the car wash and replaced it. When I did there was a small amount of stuff I couldn't get out. so I put a standard cheap metal case fuel filter at the rear by the tank, then put a new clear one near the carb. well it seems it's starving now. and the fuel pump is new (when I cleaned the tank out I had to replace it due to the crap clogging it up. so anyone else heard of this problem, the parts guy at napa and I neither one thought it should have a problem sucking thru two filters. Is there a preliminary filter sold that is more of a screen?
