What fuel line to get to swap to 4160 carb

[hz900]

If I can't get my carb issue worked out in the next day or two I'll be ordering a new 4160 carb from summit and need to know what to use for fuel line and where to buy it. I'd like to get something with premade ends on it if possible.

BTW can anyone tell me what the difference between the Holley part number 80319 and 80551. Both are model 4160 marine carbs for fords, but are about $60 difference in price.

I tried swapping my steel fuel line from the fuel pump to the carb with a S/S OEM one from SKIDIM, but it was 1/4" too short to work, so I replaced it with a S/S Braided line made up by a local street rod shop. I measured old steel line and added 1" and took the old line to the rod shop so the proper ends could be installed, $50. No more vapor lock either in the heat of summer.
