Stock fuel rail vs performance full rail

What's the difference? If there is how much of a difference does it make?

One looks stock. One doesn't. For most people, it's just eye candy. Stock rail flows enough to make some pretty big power.

^ x2, its mostly for looks. Technically it holds more and in some mysterious way might keep the fuel .3425659% cooler but i've never seen a dyno sheet that shows they do anything

You can use steel braided lines with an aftermarket rail while you would need special fittings to do so with an OEM rail... =\

Re: Stock fuel rail vs performance full rail

Stock Honda OEM (B-series fo example) fuel rails are just fine for anything up to 500HP. Once you break the 500hp barrier then you need to basically upgrade your whole fuel system...
