Help: what vacuum hoses for weber/brake booster setup?

[AndyLuft]

Hi,

Im having a hard time sourcing the right hoses for my project.
Ive tried the serach fuction without any good leads.

The car is MY ‘71 911 with webers and brake booster (and metal/hardlines infrastructure).

The tunnel hardline is there, and I would need hoses from between:
1. intake manifold (pmo centre intake runner hole 1/2’’ ) to tunnel hardline
2. tunnel hardline to under dash hardline (under the brake booster, behind the pedals)

Is there any special hoses recomended or any special needs to address (collapsing hoses for example) for this?

All experience is welcome.

Found it.

It is 12x19mm ID/OD size and can be bought by the pelican shop as «Part#: 34-33-1-115-926-M20».

I ordered 2 meters continus length of it.

Ps while on the subject, make sure you use the right type of hose for its job.

I found this as valuable information regarding choise of hose.
