Question from a newbie: What is the purpose of adding FAST fuel rails? Can they be added to an LS1 engine. If you add them what else should be adding? Is it expensive?

Looks cool!

I did a search but it did not answer my question; thank you

They're for looks only. Not needed on a stock or modified motor, but they are a nice appearance mod.

For most builds and setups factory rails work. When I got my 102 intake I just used ls2 fuel rails. For the radical builds they need more fuel and bigger rails.
