how much fuel do you think really goes through those rails?

they're plenty big enough for any motor you'll ever build

I actually had someone else say the exact same thing to me, I didn't think much of it though.

You should. Using bigger fuel rails is going to do nothing for you. Of course, you give no background to go on as far as your mods or even what you drive. That information would be helpful in procuring more accurate advice.

Stock lines do, the stock rails if modified for a parallel setup are good for way more.

I was hoping you'd chime in. So untouched rails are good for what?

A lot, I mean BLS is pushing prob 800 area at the engine and still on stock rails setup in series too.

I plan on doing the same, granted my rails aren't stock, but their same sized and 6an lines so stock line size.

I would not worry about fuel rails at all, if you really need them, you wouldn't be asking.
