anyone know how much hp stock 03 GT fuel rails can handle? running svt 255lph pump and KB boost-a-pump. just wondering cuz not once has my tuner told me to upgrade the fuel rails. only thing he's told me to get as far as fuel is the boost-a-pump.
thanks

probably a lot of power.. I know it isn't an accurate answer but blown cars with over 400rwhp seem to do ok with the stock rails.
How much HP are you pushing?

With that kinda power I would look into new rails your running really close to tapping those ones out. Plus I would do it just to be on the safe side.

Just save and buy the right parts so you don't have to buy things twice.
