Hey everyone!

I need to get a fuel hose kit for my 1971 Fury I 440 HP police car. I'm looking at my options at YearOne.

The line size out of the sending unit is 5/16" as is the fuel pump and vapor separator. But I'm confused because all of the catalogs say 3/8" for 440 & 440 Six Pack. I'm confused. confused

Which kit do I need?

Thanks to any and all who reply.
