[urq] Fuel lines

So here's some thoughts and questions about fuel lines . 

I'm replacing all the fuel lines , and I'll be using 8mm ss . 
Main reason for this is the AAN conversion , they need to be re-routed anyway , and 
the originals are in very poor shape . 

The cis has a pressure accumulator  , wich the efi doesn't . 
It's easy to keep it , it's just as easy to simply remove it . 
It could also be replaced with something like the mushroom shaped damper found on 
top of the intrank pump systems , like the fi S4 .
Fuel pump and tank will remain original for now .  

The later cars have a carbon cannister wich catches and stoes the tank vapours instead of venting them to ambient  . 
I 'de like to keep that feature . 
Meaning I have to add a third line to the fuel system from the tank vent to the carbonn cannister . 
The S4 has a 6mm line for that . 
I don't have the room for it on the urq , but a smaller line , like a brake line  would be possible . 
Any opinions on this ? 

This car will have a bi fuel system . 
In a later stage the fuel tank will be replaced by a propane tank , and I 'll add a small emergency 
petrol tank . That one will most likely have an intank pump .
