vaccum lines

Hey guys, what sizes are our vaccum lines. I wanna replace all the fugly black ones with bue or a purpleish blue silicone hoses, but the damn thing comes with 10' of 4mm, 10' of 6mm and something like 6' of 8mm. is this enough for our cars or what??? I am also planning to do this to the vaccum box whenever I have the time like tomorrow, all day project for me if they are the right sizes.

hell no. it is not enough.
i used almost 100 feet to replace all the lines.
i used 4mm ones.

any usage for the 6's and the 8's???

not really, there are only 1 or 2 hoses in that size. Oh and some for the white valves next to the carb and to the air suction box... I dunno, seems like a waste to me... I'd only buy the colored ones If I was doing the vacuum line removal.

after i swaped all the lines with blue silicone vacuum tubes. the engine looked gay. it was too much color. so i just riped it out and removed all the vacuum lines.

I used 3.96mm ones (5/32"). Mine are black and I have this really really ugly white adapter.. it's ghetto.
