What size fuel rails after stock size?

[ProjectoStang]

I am looking to upgrade my fuel rail because I don't think the stockers will be enough. What is the next size bigger after the stock ones?

AS LONG AS YOU KNOW THAT THE STOCK RAILS CAN HOLD WELL OVER 1000 HORESPOWER.

i dont think the stock rails will support 1,000 hp but they will support half of that.

94-95 rails are only good to around 550 to 600 rwhp in supercharged or N/A cars. With Nitrous its different since you have another fuel source in addition to the injectors. If you want to go past 550 you should find a good set of vortech rails.

I have only heard that the stockers support 500-600. I just want to make sure I have enough fuel. Is the next size 9/16th or 1/2in?
