What's the difference between 71 Dart and 72 Dart fuel line?

In-Line declined to do a custom 3/8" line pump to Carb for me.
I was just about to call them and ask. I'll let you know what they say

I called Fine Lines/SS Tubes (same company) and they said they'd make me the 3/8 carb to pump line for an extra $10

I hope it fits if that's what I get. If i ask for small block 1971 the line from the pump to carb should go around the front of the engine underneath the alternator bracket correct?
