So i can't find OEM replacement vacuum hoses (because they're not cluttered). Does anyone know where i can get them. Anyways, i went ahead and got 25 feet of rubber vacuum hose (for now). The question I'm going to ask is the original line seems to be 1/8th O.D. and the rubber line is 1/8 I.D. is changing the I.D. going to change the vacuum on my engine. just wondering. thanks.
