Fuel Rails - Evaporator pipe question?
 

Just wondering if someone can give me a good fix about what to do with the evaporator pipes for the fuel system.

I have a reasonable idea how the OE system runs - pipe from the filter goes along its own rail to the little bundle of pipes and Non-return valve on the drivers side of the inlet manifold. If anyone can provide me a description of the "modified" way of routing the evaporation pipe it would be much appreciated!
