The ones that go into the fuel rails from the chassis hard lines, but since you're using pre 94 ones, you won't have any issues finding replacements.What lines is everyone talking about here? The reason I'm asking is I am useing a 94-95 fuel rail on my 351W into a 1989 GT. I also picked up the stainless fuel lines that plug into the fuel rail and go down along side the motor, so I didn't have to bend the 89 lines to fit the 94 rails. I assume everyone is talking about from the end of the second line along side of motor to the frame rail, correct? The pics I saw in the post show rubber lines from the chassie up to the fuel rail and that is what has me confussed.
