the hardlines for the system are different. The line from the pump goes into a hardline that goes to the rack.
You could either find the hardlines and pump line from a twin cam or you can check out this thread

they make a line that goes straight from the pump to the rack, no hardlines, no sensor and their product and customer service is great.
I picked up a SS line and its pretty sweet just waiting to put it in but install is pretty easy it goes directly into the pump to the rack.
