I hope some one can help with this..

I need to know which fuel line connects to which port on the fuel tank? There are two lines to each tank (front+rear), and the factory couplers will connect to either steel line on the fuel tank.. How do I tell which fuel line goes to the right steel line port?

I know if they get reveresed, I will no get fuel as its a return line.. Any help would be awesome!

 

Not sure what it is your doing/ working on. Here's a bump.

 

I believe the two lines are different sizes, look where the braided line goes back to a solid line and line them up to the tank fittings accordingly. Hope this helps.
