What sizes and lengths of vacuum hose do I need to change all my
vacuum hoses to silicon in a 93' SE-R? Thermaflex 'thinks" 3 mm, 6
mm and 10 mm in 10 ft. lengths, but they are not sure. Does anybody
who has done this swap know?
I got a Kit from a local AutoZone store. I believe it had like 10 ft. of 10mm and like 2 ft. of 4mm and 6mm. With this one kit I did my 91 Classic and my cousin's. You will use mostly 10mm on all the vacuum hoses. I managed to get a 4mm hose to replace the radiator to over fill tank. It was too big but after working the stock clamps on it shrunk until it fit. I couldn't find a use for the 6mm hose.
BTW: the kit costs $19.95
