I have the same problem on my T. I'm going to run 3/8" hard line for most of it and use short hoses at the ends.

I did the same thing on my 46. There is a hard line on the engine that runs over the rear of the block and down close to the frame. A short piece of hose makes the jump to the frame and hard line runs back to the booster. Another short hose conects the hard line to the booster.

The hard line can be regular steel(like fuel line) or stainless. Make sure you use vacuum rated hose and be sure to use clamps.

Hope this helps. Sorry I don't have pictures.
