asked by on May 28, 2017

2016 Nissan Altima, what are the fuel lines that run underneath the car under driver's seat? Is one a return if so which one? There are 4 lines that run together I believe two are fuel and two are brake. One is a fuel line that's pressurized if I'm right. Is the other one a return or a vapor or what?

My car has 14000 miles.
My car has an automatic transmission.

Hello. You will have two brake lines, a pressurized fuel line, and an evaporative emissions line. The smaller metal lines are the brake fluid lines and the other are fuel system lines.
