To start... .
Welcome to the TDR!
As soon as you can... please update your signature to tell us what you have.
Some guys don't like to put the state... . I prefer it... I can give advise, or show advise depending on if you are local to me.
Pics of fuel plate installs... . You need more of a movie for that. Really... . it's easy.
Star wheel... . Open the hood. Stand at the drivers side front tire. Look at the injection pump. You will see the injection lines, then a domed housing with an 8mm allen head plug in it. Under that plug is the star wheel.
Furthermore... Remove that housing and your fuel plate is under it.
My recommendations... . Don't play with it, till you do some more research. You can do engine damage, as well as pump damage if things should go wrong.
If you want more info, let us know. I admire a guy who will dive in head first, but in these trucks, doing some research can save you a TON of $! If I knew then what I know now I wouldn't have spent near the $ I have.
