99 Suburban 2500 454 Fuel Injector Retainer Clips

[bluex]

I would think you could remove the retainer clip carefully and pit a new O ring on the line. Should not be to hard to figure out a way to retain it securely.

I found another one but I do still have it as a backup since they are so hard to find. It was just a small leak. I considered epoxy before I found the replacement as that might have done it for a while anyway.
