Where is the fuel filter located on a 1979 Chevy El Camino?

lets assume that this is a factory setup and no modifications have been made follow the fuel lines from the tank to eliminate these mods. look for steel lines running along the frame from the tank. look for line installed mods such as electric pumps and or filters. there were none of these from the factory however these need to be eliminated. the factory installed filter is at the carburator. where the steel line attaches to the carb un-screw the line there is a larger cannister on the rodchester carb here that also unscrews do this with a cold engine to avoid a fire. the spring loaded filter is directional and needs to be installed in the same direction
