Don't use the white vinyl/plastic line they included with the guage!!
I had one of those lines break on me once. If that happens, you'd be surprised how quick your engine can pump itself out of oil. Luckily for me, it sprayed right on the header so I could smell it and only lost a quart or so.
Go and buy copper tubing from a place that sells fittings and that sort of thing. Its easy to bend and route into position and won't break open like the plastic crap can.
