What line do I need to cut on the e30 to do this and what side of the car is it on? Anyone have a picture? Or description so I install the check valve on the proper hose

Thanks guys!

I pulled out the backseat and it looks NOTHING like that. There are two lines that seem to connect the two tanks(you can barely see them through the little door you remove. There is 1 line on the tank.

My car is 1989 325i coupe

It says to put the check valve as close to the pump as possible. So is that one line coming out of the pump on the passenger side the high pressure I need? It goes straight to the fuel filter?
