I have installed Inline Tube SS lines on a ‘49, ‘50, and a ‘52. Only issue was learning the importance of repetitive tightening and loosening and tightening of the flare ends to securely seat the SS flares to the inverted flare parts.
I do this on steel brake and fuel lines also, but is especially important with SS flared ends due to the stubborn nature of SS.
