The common vacuum size is 4.2mm. There's reference in the FAQ to 134" needed for the entire engine (B230FT) of 4.2mm; 26" of 6.6mm (this runs from the intake manifold to the fuel carbon canister) and 12" of 3/8" hose for the brake booster. I believe there's also a short section of 3/8" for the check valve which connects at the top of intake manifold.

You can check the vacuum hoses on your car to confirm. Following the part number, there should be a diameter symbol (0 with a diagonal line through it) followed by 4.2 (for example, for 4.2mm).
