If I recall correctly, if you decide to use a factory return line, it crosses the engine cradle. therefore the engine needs to be lifted up out of the way to locate properly.
I remember making a mental note to have the fuel lines in before I reinstall the motor.
I was worried about that. Looking around on this site and at some diagrams, I'm having a tough time of deciphering the routing. I'd hate to buy a new line and not be able to get it routed properly. Can anyone describe the return line routing to me or maybe post some photos that show it? Has anyone tried to place a factory fuel return line with the motor in place?
I suppose if push came to shove, I could just make my own lines.
