Hay, I just did this yesterday. No schematic, but I'll try to put it into words. As the hose comes from the capping station, run it into the hole in the top-front, left-side of the pump. As soon as the hose is in this hole, route it toward the rear of the pump and loop it back around 360 degrees to go out of the hole in the rear of the pump. This is for the black side only. The color side is much easier. Hopefully, I'm not the only one who can follow my directions. The OEM hose is that white, latex-like, soft hose. I think it's the best. There is also some clear hose out there. I think it's not soft enough to work well. It's like the gas line you can buy for a weedeater or a RC airplane.
