I ran a search and I believe I came up with the answer, but I want to double check. While replacing the intake manifold lower gaskets, when I went to put the fuel lines back on the rail I noticed what looks to be an o-ring groove in the line that goes in the fuel rail closest to the firewall. This line has the accumulator can on it. There's no o-ring inside the rail or in the groove of the fitting. Should there be one?

When I ran the search what I came up with is that it should be a green o-ring. Is this correct or are people refering to another o-ring in the system?

Thanks for the help.
