I've read several posts about people removing and replacing the factory ballast hard tanks for many 210's (V-drives) not much about people removing the hard tanks for the 216's (V-drives) and directly replacing them with sacs. I'm hoping the hard tanks can be pulled and with minimal alteration to pumps and "plumbing" just some sacs added on. Has anyone done this "plug-n-play" on their D-drive? Any photos would also be greatly appreciated.
