I am planning to "dress up" my engine with colored vac hose , flex fan , some nice paint work , and tlc . I seem to be having trouble with the sizes of the hose are they metric or fractional size ... and what sizes are most of the lines (3.5mm and 6mm)


by the way I have no rats nest and it is a 12a w/ stock nikki carb


also what is the best place to get the silicone hoses
