Hi Ed,
I originally mounted it on the vertical shroud support. When I added the alternator, the tank had to be moved back to clear. Functionally, the hose length doesn't matter much. I DID replace the clear hose with black, once I was sure that things were working. There are many tanks & ways of connecting them that will work. It's what ever suits your taste. I like the sight tube on the side of this tank. Of course you could use a cheap see through plastic tank.
