Need some parts help

[EVO-lution]

Ran a search On the forums and google and really didnt find what i needed. I have some questions about fuel systems. I have a 03 mach 1 and i have a 04 cobra fuel hat. I want to eventually make big power. Would i need new rails or will the stock mach 1 rails be good to make 800+rwhp. Also if i got 2 walbro 255lph fuel pumps would they be sufficient enough to make over 800rwhp. I'm not very familiar with fuel systems yet so i'm tryig to get a better understandig. Please help

I dont think two 255s will work well with 800 plus rwhp esp if u use e85 .U honestly need a complete return fuel system. At bare minimum lethals budget kit. Twin 340s or twin 405s would more likely be up to the task.

What i ran the 2 255lph in tank pumps along with the A1000 kit lethal performance is selling? I mean i may hold off for now since the car wont be turbo right away. Or just run only 5-600hp for starters. But once i'm stationed back in the states i want to go balls to the walls
