HELP air bag suspension Q45/Y33

Can anyone help me out, im trying to figure out a good way to be able to run the air line hose from the trunk to the rear bags for my brother. I was wondering if anyone can tell me their set up, or show pictures of the set up, it would be greatly appreciated.

i run them under the car right inside of the pinch weld and over the subframe.

i run on the inside of the tunnel, so if ou are jacking your car and you slip the pinch weld it doesnt crush a line

look at my build thread i used 1/2" od lines so it should be alot easier with 1/4 lines
