Hi Ian and Judy,
I also use the same filter that you specified. I use 2 micron filters in the racor with no problems.

Hi Eric ,
You’re right . When we bought Pen Azen we had Amel fit a big truck filter in line with the diesel intake . In the starboard cockpit locker we have a cock in the diesel hose which allows us to fill the tank either directly ( if we are confident of the fuel quality ) or divert the fuel through the big filter , propelled by an electric pump , and then into the tank .
Back in EU waters we rarely use the big filter but it was very useful elsewhere.

You forgot to mention your pre-fill filtering system. Thank you so much for that idea. I think I have about 86,000 miles on Kimberlite and never had a problem.

Can I encourage you to identify yourself, the name and number of your Amel and where it is ? Its just makes it easier for anyone else to respond.
I do wonder about the necessity of fuel polishing. We have twin Racors before the engine fuel filter itself and only once in almost 30 years of owning three Amels have we had a problem with dirty fuel, a problem quickly fixed by switching from one Racor filter to the other. This is despite 8 years in third world countries with few leisure marine facilities
What is rarely mentioned is that diesel engines recycle back to the fuel tank more litres every hour than they consume. With the D2-75 I'm told that that can be as much as 75%. The effect of this is that you automatically have a fuel polishing system in place.
I should be interested to hear of other experiences.

Any opinions or better ideas, would be well received.
I am thinking of rigging a simple fuel polishing system that utilises the existing Racor set up.
Between the Racor filters and the engine insert a Y valve that goes to the engine or to a new inline 24v fuel pump (120 lph) that then goes to the fuel return line with a T connector.
In polishing mode, in a harbour or at anchor, with the engine off, the Y valve is set to send the fuel to the pump which is turned on, and back to the tank via the fuel return line. The fuel is circulated all day or overnight and is filtered.
At the end just go back to normal mode and change the filter, check for debris.
Any thoughts? Total cost would be £45 for the pump plus a few fittings and a bit of hose. Call it £100.
