Do you mean parallel? The typical system allows you to have both filters installed and switch which is the active one to ensure they never clog at the same time (there is always one in reserve).

If you are going to run two filters in series then you want the second filter to be finer than the first. This extends the life of them as the first only traps larger particles and the second grabs the small stuff. Frankly I don't think this offers much that a single larger filter doesn't.

Exactly. Happened to me off the North/West point of Cuba and it was not nice messing with fuel in that situation. Turned out to be a blocked fuel line at a 90 deg. bend at the top of the tank. I never did know if it was asphaltenes or biological because I didn't know, at that time, how to tell the difference. A few drops of bleach will tell you. If it changes color it is biological.

There is a thread on the forum and a post from Jedi with a schematic of his fuel polishing system. It is worth the search. Use the google custom search box.

Re: Polishing diesel fuel

A water drain in the bottom of a tank will cure almost all fuel problems on a boat! That is if ya drain the water out offen! No water no growth! At least it's worked for me !

Perhaps this will help. I fabricated mine, and it is likely more than most need, but I have 2,400 gallons to maintain. This system can be scaled back to a single, non redundant configuration if need be.

I have the 900s and they separate water just fine.
