This is an 82-87 Camaro/Firebird fuel return line for carbureted V8 cars. This line runs from the tank to the pump and is CNC-bent to factory specs. This is a 5/16 inch line and runs along the passenger side of the car. These high quality lines are made in the USA. This line is stainless steel so it will last much longer than normal steel lines. (Note: Because of the length, these lines have a "shipping bend" that needs to be straightened by hand prior to installation.)
