Factory Correct Fuel Line

[gwp4]

Hi Camaro experts:

I have a 1968 Camaro 327/210 hp V8 LF7 sb base model with a build date of May 14, 1968.  I'm very interested in learning the correct fuel line size for the car.   I've heard both 5/16" and 3/8" and want to know what the factory installed.  Getting it back to its original condition.  Thanks.  gwp4

1968 Camaro's with V8's had the 3/8" fuel line. Only the L6 had the 5/16".
