Generally
Vacuum tube 76 cm long, Between carburettor and distributor vacuum bell. It is not fully bent but a straight pipe, which you bend yourself.
Shorter pipes are delivered straight, the longer ones are bent to keep the shipping cost down.
We also ship the longer pipes straight. But shipping will then be more expensive. If you want the longer pipes sent straight, you cannot order them in the web shop. You have to call or send us an email about this and we will arrange this manually.
