Diese fuel filter / fuel polish system

The attached is another idea that I found to be essential for any boat intending to go cruising. Outside the U.S and even in the U.S. the fuel can be dirty. This fuel can have water and sediment that will quickly clog the filters. This system cleans the fuel of most of the water and sediment before it reaches the fuel filters. You will find that you will rarely have to change your filters if you use this system.

I realize that this is covered in my book but this attachment explains how to build and install the system.
