It is on piece that connects fuel line to fuel filter on 93 Camry. A crush washer is used to seal off this surface but has scratch going from OD to ID.. It had to of been there before I took line off, and the banjo bolt was on very tight. I don't want off the part to surface grind if i don't have to. I'm wondering if these is some epoxy or ? I could use to fill this very small and shallow scratch. As I said a crush washer is going over this surface.
I've tried stoning and its not going away. Any ideas?
