Killer dowel pin, it's a pin in the timing case, used for alignment that can back out and fall into the timing gears, causing major damage.

You can't see the fuel plate itself from outside the truck , you need to remove the AFC housing, it is not hard to do at all , there is one "break off" screw , that can be a pain to remove sometimes , but not always , other than that , 4 bolts and it pretty much comes off (some people remove the intake horn) , unbolt the plate , bolt the new one in , adjust the goveroner lever , and put it all back together.

You can purchase a GSK from lots and lots of vendors, I got mine from Piers Diesel Research www.piersdiesel.com

 

A quick visit to the Tech Facts section can alleviate much of your anxiety
