Ok guys sorry i have not been on in a while but have been busy with work and school. I know this belongs in the 99-04 section but i mainly come here for my answers and i need a fast answer.

I have a question for everyone here that has messed with their fuel pumps. Is there any difference between the 00-04 GT and Cobra tank. My friend wants to add cobra pumps to his car but his mechanic is telling him he should buy a Cobra tank aswell or else he can not use his new fuel pumps.
