I don't believe this system uses a return line. There are a couple other similar systems out there that give you a choice of a setup that uses a return line or one that doesn't, but this one appears to just use a single line with an external fuel pump and regulator. I have read some reviews that said the external fuel pumps were a bit noisy, but it would have to be real noisy to overcome the air leak noise, the stereo noise and exhaust noise I have for it to be of any concern to me
