Quote: [don't know about 701 e bodies but 69 B bodies with 440's got 3/8 main lines so I can't see the 6pk in later years not having it either , only 440 car I know of that got a 5/16 line from the factory was the 69 A12 cars .
All 68-69 440's (including A12's) had a 3/8" sender and a 5/16" fuel line. 70-up got the 3/8" sender and fuel line. All had a vap. sep. with a 1/4" return line.
