Yup, dealership charges $12 for this oring.
If I had time to spend to find an aftermarket replacement, I'da been looking.
So got the oring installed, and no more fuel leak. At least at that point. Had another at the regulator. Easy fix. Removed line and reseated. No leak after that.
Then, there was the coolant line Oring. That one was $5 or 6. But now I have a whole nother issue if ya'll are bored. It's in a new topic.
Thanks for all the help ya'll.
