PGMIII for unleaded / pump fuel part number 30400-NKD-700, avgas part number 30400-NKD-840

On mine there are numbers inked onto the top edge in faint blue lettering. I'm not sure if this is normal or not and whether it may wear or wash off over time. As with most things, you need to feel comfortable the seller is genuine and trust they tell you what it is you are buying.
