What are you trying to do? Upgrade? Or just replace old stock parts?

You can use any regular Focus fuel rail. BUT you will have to hook up an external fuel pressure regulator. (All Focus Zetec's are a non-return style system.)

Any high-impedance Focus Zetec injectors will work. If you go to bigger injectors, you need to reprogram your PCM. If you don't you will run very rich and eventually throw a CEL. BTW, CFM has very good prices.

There has been much debate on the stock injector size. Most people say either 16lb/hr or 19lb/hr. I was just looking at some pictures of my stock injectors and they have a 20 stamped in the side. This leads me to believe that they are 20lb/hr. That proves the calculations in my previous thread.

Here are some pics of the stock injectors. Beware, they are very large detailed pics.
