I need some hydraulic info websites

I don't know too much about hydraulics, but I need to do a crash course on them so I can do my homework(doing a presentation between air ride and hydraulics).

I need to see simple diagrams on how the hydraulics are installed. I also need to know EVERY single part needed to do a FBSS setup, and what they are used for. I need to know some pros and cons about hydraulics(allready know them for air)

Any help would be apprcieated, thanks.
