Yes my 2000 GT had returnless fuel lines and it was a vortech kit all you needed was bigger injectors and custom chip worked great as reliable as stock. How do I know if I have returnless fuel lines anyway? I have a 99 SVT did they have them yet? I would like to get a bigger in tank pump aswell, are there any available for our car? I was planning on doing a custom chip burnt on a dyno anyways for the supercharger those are always the best. Wonder what size injectors I should use? maybe 24lb
