I just purchased "Dorman 800-027 Fuel Line Retaining Clip for Volkswagen/Audi" from amazon and verified that they are a suitable alternative for the broken blue clips. Unfortunately I couldn't wait and ordered the fuel lines as well. Anyway, learn from my mistake, save yourself the $30, and buy these $3 clips.
