Now that's a good ideee , i ordered new sites when i ordered my wheel pants, i was going to have some glass tubes made and put a bead inside of the tube ( since i burn mogas and its almost the same color as the tubes) and I still might if i can find a bead that will float in fuel and not decompose , although I'm not as old as you's guy's its tough to see mogas in the tubes at times since it's not that purty blue , maybe the mogas makers could put some dye in it so when us mogas burners will know when we need some Mo' Gas ?
