            Perfect fit

            What can I say? They fit perfect and my fuel rails dont have any leaks. Top quality product. I would definitely recommend these.

            Beware this is only one fuel line’s worth

            The O-rings themselves look fine. I have not yet installed them so I can’t speak to how they feel and fit on the lights. The biggest issue that I had was that I had assumed that one set would take care of both supply and return lines. They did not- there’s only enough O-rings for one line. It would be better for American muscle to note that in the description.

            Simple straight forward original O-ring replacement just remember to lube your O-rings with a light oil or Vaseline before you install!

            5.0 Fuel Rail O-Rings

            These are fairly hard to find, I bought several pair. The Dealer wants to sell the entire Fuel Line.

            Fuel line O rings

            These O rings are great, just like OEM. American Muscle has been the only place I could find them. With a fuel leak I was unable to drive the car. Thanks AM, for the help when nobody else could.
