Supply line is clear, but the return line from the fuel distributor is plugged somewhere. Trying to figure out what I can rod through it, but so far no luck finding anything. Weed Eater line doesn't have the toughness to go through, and chemicals are having no effect. I really don't want to make a new metal line. Since it's just the return, I was thinking of cutting a piece of the metal line out and replacing with rubber fuel line.
