Contact the company of your choice for their fuel polishing specifications and schematic. Each company sets their systems up a little different. My system is fairly compact. However, my system uses an additional "paper towel" filter beside my big Racor filter - the fuel is pumped through both. The company recommends using only 'Bounty' brand paper towels. The paper towel container is about 18" tall and I need another 18" vertical clearance to change the role, so a total of 36" vertical clearance.

We'll have a total of 2400l in 6 main tanks pumping up to a gravity fed 150 l tank x2, 1 for each motor.
Yes, the 150 l tanks are your "day tanks." That would make a well thought out fuel delivery sytem.

Most times we figure on having about 1000l on board and the other tank's empty to save weight, and add to performance/economy.
I'm not sure keeping one tank empty is a good idea. An empty fuel tank leads to condensation inside the tank. From a fuel maintenance perspective, it is better to keep your tanks full in climates where you experience high humidity (which is anywhere on the water).

We also want some form of fuel polishing system on board, and I really need to get the spot sorted for that ASAP.
You will really like your fuel polishing system. In my opinion, they are an essential piece of equipment on any long range ocean cruiser, especially a power boat.

Do you find that you use a lot of filters?
No, I have my fuel polishing system for 5 years and I have never experienced contaminated fuel or dirty filters. I just change the filters as part of my normal engine maintenance. No stress, no strain. I usually leave my DC fuel polishing pump on 24/7.
