Well, I purchased an A12 new in the spring of 1969 and in upgrading to a electric fuel pump from the back frame rail,
I can unequivocally tell you that I replaced the 5/16" line going to the mechanical pump.
I'm 81 years old and have pictures of my car on the carrier next to my buddies (a salesman at the dealership) M code Barracuda.
Those were the days!!!

I agree, a buddies Dad had a '70 Hemi 'Cuda, 4 speed, all stock, was selling it in 1975, I couldn't come up with the $2,000 for it, it wound up in Alaska. I've never seen factory 3/8" fuel lines on a mopar. IIRC, Dave Dudek extrude honed his factory 5/16" fuel lines to get a bit more flow?
