Someone more knowledgeable will hopefully chime in, but for now here's my two pence worth! Both hoses run from the reservoir above the back of the engine in front of the heater box, then forward along the driver side inner wing. I sheepishly admit I don't know which is the supply and which is the return. Doh! One goes down in front of and below the radiator, across the inside of the front valance panel, then back into the bottom of the engine bay to the pump unit. The other goes from/to (?) the pump, up above the timing cover, and on my car through the alternator bracket, then back along the drivers side inner wing, up across the back of the engine in front of the heater box, back to the reservoir. I don't know exactly how long, but they're both really long! Couldn't find a helpful photo I'm afraid. Hopefully somebody else will!
