While installing a new down-pipe and 4in. exhaust I broke off the fuel fitting from the fuel pump to the back passengers side of the head up next to the firewall. this is the one that threads into the head and then the fuel line threads onto it. It is male on both ends and the one that goes into the motor is smaller than the one that the fuel line goes on. Also, is ther an o-ring on this line I need to replace?
