I just got to looking under the 69 bird I just purchased and noticed that the fuel return line runs out of the fuel pump and has been capped off back by the gas tank. I know that in 2004 the tank and sending unit were replaced with a new 69 GM?Camaro units. Also the car has a Holley Avenger 570 Carb and a Performer Manifold. Is this setup OK or should I work on getting the return line hooked up?
