You can get the hoses from Nissan. Their parts catalog lists the diameters and length, and they are just cut to length from generic stock. Likewise they can get them for B110 Datsun 1200.

wish i had an exact amount, there's a whole lot I remember, seems like 2 generic metric vacuum line kits was more than enough.

Thanks.

Well... you have a ton of emissions hose, unless you want to re do it silicone, just buy a bunch of the right size, there's only about 2 or 3 sizes used for nearly all of it.

at one point i had redone all my vacuum lines in silicone and hooked them up correctly even.

Silicone isn't a good choice for things that carry fuel vapor.

Hey guys. I plan on replacing all the vacuum hoses under the hood.
I don't see any kits out there so if someone can give me a run down of the diameters used and the amount of hose I would need that would be great.
This is for a 1981 Datsun 210 with the A12A engine.
