Fuel Polishing onboard

I have been reading as much as I can find about keeping fuel clean. I'm wondering how many have a fuel polishing system (something more than the standard fuel filters) on your boats?

Think you will find that most of us here with fuel polishers have a pump with a water separator / filter.

We have been looking a several boats, none of which have anything more than just the standard engine fuel filters. With what I have read so far I think that apolishing system would be something we will add.

Does anyone know which boats are standardly equipped with a fuel polishing system straight from the factory?

We have one that 's a simple set up . It has filter , pump , push pull switch , and wire with alligator clips that I attach to nearby generator start battery . The suction side is plumbed to all 5 tanks . The discharge side is just a long open end hose that reaches to any of the tank deck fills . It's kind of a home boy type rig but it works .

Marty, what filter do you use, and do you some way to extract the water also?

We have Alfa Laval and I recommend it on a boat that you cruise offshore and long distances. Now that's not to say for one moment fuel problems are confined to that use. You can definitely have them coastal cruising in the US but then you are within the towing areas. And if I was in an area without tow assistance, I'd probably get one.

This is the unit that the Chris Craft came with. But it was not factory installed.

Mine is a Racor 1000 with a 30 micron filter. I installed it to do both fuel polishing and fuel transfer between tanks. Mine draws from the lowest point in the tank where water and heavy impurities would collect. Typically suck the bottom of both tanks every few days to empty the corner. One of the nice features of using a clear bowl separator is that when you first turn the pump on, you can see if any thing has collected there.

If you buy a boat with a polisher or you add one, it's important to verify you are drawing from the very bottom of the tank. Much less effective if you aren't removing any water in the bottom of the tank.

We are set up with 5 tanks. The one tank is a day tank that will last about 29 hours of cruise.
The 5 tanks are plumbed into a pump that will move fuel from any tank to any tank. It has dual 30 micron filters. Unless there is a reason (long distance travel with questionable fuel) we only run one water separator at a time.

The key is to get clean fuel, keep the tank fills sealed, and use desiccant breathers on the vents.
If i was going to take on questionable fuel i would pump it into one tank and filter it into the other tanks.

You can polish fuel all you want, but it's just a band aid. In a larger tank you will never polish a tank clean and will keep having issues until you get the tanks cleaned and fix the problems.

Most fuel polishers are nothing more than an extra stage of filtration. To the OP, suggest you read about fuel filtration on boatdiesel.com.

Nordhavns with their day tank setup seems pretty thorough and once into larger boats the penultimate is an Alfa Laval as BB mentions.

Boating destinations trumps all IMHO. If you can't t good fuel then some sort of additional filtration seems wise. Many get lulled into thinking that a lackluster fuel polisher is more important than buying good fuel, uh uh.

They aren't polishers then. They're just additional filters.

From everything I have read this is true, there is more to polishing fuel than just additional filtering.

And just exactly what would that be?

Walt-here you go-

The difference between Fuel Polishing and Fuel Filtration | Diesel Fuel Cleaning

Until your question, I actually didn't know all that stuff, especially the part about fuel lubricity.

We have an ESI system onboard.
