Hey Joe I don't know where you are in Ohio but you can pick up your lines at Fine Lines direct in Wadsworth and avoid the lines bent in half when they ship them. I had 3/8" on my Savoy when I had a 440 in it and when I changed to a high volume pump and 493 I switched to 1/2". I never had issues with the smaller line I just was changing every thing else in the fuel system so I just upgraded to a cleaner system with smoother bends
