I need to replace pretty much all of the brake lines on the 78 f-100 with manual brakes. Does any one know where I can find a list of lengths and sizes for all the hard lines? Appreciate any help.

 

The size is 3/16.

Buy the longest length you can find, and use factory bends as a guide.

 

Your local autoparts store can tell you the length and sizes you need if you give them the locations, i.e. front right etc... I usually buy mine an inch or two longer than what the book calls for, then add a bend or coil if they are too long.
