just a few questions about interchangeability of tanks in as bay,my original one is an early style one which is full of rust and crap.I have a tank out of the 76 i wrecked ,the shape is the same ,i know the sender is different but it has an extra breather,so do i just block it off or do i get another early style tank which has the breather in it? pics to tell what im on about
breather pipe
76 tank no breather

https://www.facebook.com/FlatFourI don't know an awful lot about Kombis, but I do know a bit about tanks and breathers.
Prior to around 1976 car tanks generally vented to atmosphere via a tank cap with a breather in it. Around 76 manufacturers started fitting sealed tank caps and venting the tanks to a charcoal canister or similar vapour storage device. I'm guessing Kombis were similar.
If you use your 76 tank and block the breather, you must use an earlier cap that breathes, like the one from your old tank if it fits. Otherwise, use a non-vented cap and plumb the tank breather in somehow.
If you use a non-vented cap on a non-vented tank, then you will come to a halt within a few km as the fuel pump causes a vacuum in the tank, until the pump can cope no more and the fuel supply is starved completely. If the pump is strong enough, you can even dent the tank! THen when you remove the cap heaps of air will rush in and the car will start again. (BTDT 🙅 )
