Does anyone know how many feet of vacuum hose would be needed for a total replacement? I'm contemplating a Turbo Control Valve from iPd which recommends the three hoses replaced with a silicone tube, at about 7 feet of length for the three. But, I'm thinking of doing all the vacuum hoses while I'm at it, as I'm starting to get some dash condensate on an air-conditioner day (which tells me that the dash cold air is redirecting into the defrosters.)

Are they the same diameters? (The TCV hoses are 5mm inside diam.)

Any thoughts or experience?

Thanks.
