..... or if you buy a boat in Annapolis that had been baking it's 2 - 75 gallon tanks in the sun more than being used in the previous 2 years and the engine dies daily because of a clogged filter from day 2 through 8 of your self-delivery to Rhode Island
So I went all out and installed a Filter-Boss system that does all of the above -
Andy Keenan, the owner of Filter-Boss is a great guy to work with and even made a house-call on my boat when I thought I had a problem with my install (his schematic). Of course the fact that he lives closer to my boat than I do helped a bit
I have 2 lines out of each tank so with a few valves I'm able to run or polish in every imaginable way from/to either tank.
Many people have made their own setups for less money but it was 'Boat Show Discount' time when I was ready so I went for it. There is a home made setup out on the NauticatUSA site.
