Re: 1969 250 i6 soft fuel line size

Smart money would be to buy the sender with the 3/8" line if you are replacing it, and use an adapter to reduce the line the rest of the way. No point in buying things twice, and an adapter is cheap. FWIW, I put a 4 barrel carb on my '64 Malibu with a 283 and a powerglide trans. Same 5/16" fuel line got me to 120 MPH. How fast and quick do you want to go?
