I have searched high and low for a replacement retaining clip for my fuel filter. I have 3 points on the filter and I broke the ring clip off of the inlet line (I'm an idiot and tried to pull it out instead of pushing it in). I was hoping that someone could provide a definitive answer with a part number.
In my search I found a part number that fits earlier vw's and it looks like an exact match but I don't know for sure.
800-021 is the aftermarket part....

Edit...I bought that part and it does not fit. back to the drawing board.

I find it hard to believe that I am the first person to ever encounter this issue.
