fuel line

My diff cover is contacting a line coming off the fuel tank - 2000 Mustang GT. Am I smashing the hell out of the return line? If it is just a vent or pressure relief line, I won't worry about it as I will be installing the return style system soon. But if it is the return line, then I'll need to...

I have a Fore Adapter AND the line that connects from a Fore Fuel Hat to the stock filter / line. I didn't need it with my build so on to the next person who may need it. $75 shipped.
