The lines wrap around the engine in two columns and seperated by plastic spacers and tied together with the metal bars, screws and nuts.
The outermost column is 4,5 and 6. The innermost column is 1,2 and 3. I don't remember which is on top but is pretty obvious when you hook it up. The fittings on the pump go 6-1 going from front to back.
I hope this helps.
