    motorcycle carbs...return line?

    I was bored and not ready to start fabbin' my manifold for the Mikuni's, so I grabbed a sawzall and hacked apart a stock manifold so there's pretty much two Y's from the ports. I have a pair of Keihin PWK 38mm carbs, one off of the kart to the left, hogged out the intake and slapped them on. I figured out the throttle cables and fuel lines, up to the returns...... I was pretty sure that the hard line coming out the firewall is to the tank, part of the EVAP system, is this true? Is this enough (or usable) for the return line (excess pressure) from the carbs to tank? Is there another breather to allow air into the fuel tank(maybe the one on the fuel filler?) I took pics too, when i get them developed i will scan in and show alls...... thanks in advance
