Reading and editing other peoples code while using the wiki as reference is a good way to learn, providing you limit it to small sections of code. Using large chunks of code as if it were your own is shameful.

In response to the OP's request:
It would be very difficult for anyone to show you how to script what you are asking them to, without access to the full script ( which nobody really wants anyway ) Furthermore, unless you use a special plugin, or run the entire fuel system inside a filterscript, there is no simple way to do this with a filterscript.
