my moms resto of a 73 mustang is ready for the fuel injection system. i need a good way to plum the return line to the tank. what is the best way to do this. i have a new tank that hasnt had gas in it yet. and the sender has been out for about a year. so if i need to weld a part on i can do so. i have a state and government certified welder person at my disposal for this job if needed. thanks for the help.
