1967 440 Fuel Pump to Carburetor Line

Can anyone tell me if there were any differences between the fuel pump to carburetor lines on a 440 Magnum from 1967 to 1968? I'd like to replace my original line as it's a bit faded looking, and I'm missing the lower "loop" section from the fuel pump to the fuel filter. However, Inline Tube only lists sets from 1968 and up. I'm wondering if there really is a difference, or if their listing just incorrectly omits 1967. The only difference I can think of (from memory) is that 1967's used an AFB, and 1968 and up used an AVS. If this is true, are the fuel inlet positions different between the two, necessitating a different fuel line? Any input is appreciated.

Cheers!

Year One shows different PN's between the two. No images.

3/8" or 5/16" line? Fuel pump outlet maybe located differently.

Thanks for the input. I did some further checking, and it seems to be an AFB vs AVS thing. I contacted Herb's, and he's sending me out a kit that is supposed to be correct for my year. I'll update after I receive the lines.

Thanks!
