adapting mustang fuel lines?

. The fuel lines...well then. The good news is, with an in-tank or in-line fuel pump, you're okay there. But getting the lines to the motor is another story. The metal lines going to the motor are okay, but they need to hook into the rubber lines before that. So this necessitates finding a way to adapt your stock lines. Ford does make a nice kit (p/n N803431-S) that makes life easy for you. It's two unions and 4 clamps, used to convert your existing lines over. Cost for the kit is around $10. If you find your car cannot use this kit, you may have no other choice but to run all new fuel lines from the tank to the engine.
Here you go straight from Eric's site so if it's not right its his fault :D
Hope this tells you what you need
