I am a chevy guy that just aquired an 03 gt and a 98 mark 8 dohc with 53,000 miles. I dropped the motor in and realized that it has return fuel lines and the gt does not. I don`t want to spend 6 months and $600. to swap in a cobra intake. What is the next best option ? How can I change the gt to a return fuel system ? Fuel pump from newer gt ? What are my options on the return fuel problem ?
