Hi I have just entered the world of rc Hydraulics and I ran into some problems hooking it all up. Joe from little giants came to the rescue and gave me a link to this

if you look through this manual you can see on last page (32) a basic drawing of how the system needs to be hooked up. It also gives you a good idea of what you need to order
I hope this answers the questions that I had and helps you get going.
thanks for the help Joe.
