I hope you mean "Fuego Ironworks". Here's how it's done: You first have to get to Floroma town.Make a right (well, that's the only other exit), and keep heading in that direction. You there have to battle some Galatic Grunts and commander Mars. Then, you get on a bridge and surf as far as you can go.
You have to surf up a river from the Valley windworks area.
You can get two in Fuego Ironworks at the entrance to Etarna Forest (from Valley Windworks)
go to the fuego windworks. use surf to travel north until u see land that was unreachable before. search for a factory on the island (easy to find) and there u go!

route 205 south, valley windworks, fuego ironworks (fish with super rod) it's rare good luck :)
it is on route 205 (the floaroma side), the valley windworks and the Fuego ironworks but you need a super rod to get one.
Pachirisu is avalible in Pokemon Pearl in: the grass near Valley Windworks, route 205, and at Fuego Ironworks. Hope this helped, Lilmomo1
