Videos from PaBioDiesel show it working with WVO on a 55 gallon drum. There's no reason why you can't modify their setup to work with a fuel tank. I'll be doing that when the time comes. It's a small system. All you need is a pump (I'll be using a power steering pump, likely), a way to warm the WVO (plate heat exchange with hot antifreeze running through it) before it hits the pump and the centrifuge.
The especially appealing part of using a centrifuge vs filters is that you can clean out the centrifuge any time instead of carrying an arse load of filters. You can clean the centrifuge with a couple paper towels. No reliance on a source of filters. WVO filtering on the road requires many, many filters of all sorts of microns since you won't have time to let the WVO settle. You'll be swapping them out every 500 miles (estimate based on my brothers experience with doing the same thing on his wee VW Jetta).
A centrifuge also acts as a water separater.
