Re: Fuel polishing

Hi Nick,
At the bottom of my fuel tank there is a valve that shuts off the fuel, it is connected to a rod on the shelf in my Mid-ships bunk that will turn off the fuel from outside the engine room if there is a problem in the engine room.
FYI, behind the valve on Kimberlite there is a mesh screen that is factory installed to keep large stuff from getting into the fuel line.
After my racor filter there are neoprene hoses that go to the genset and engine. If you wanted to put a valve in the line to polish your fuel this is where I would put the valve.

Hi Erik,
I am not on the boat now. From memory the fuel exits the bottom of the tank directly to the Racors but There is no valve on a lower sump.
I could drain off the Racor filter very easily. I suspect though that the pick up is just off the bottom of the tank. So the sludge will remain between the fuel pick up and the very bottom of the tank.
There may not be any sludge. Maybe I am seeing gremlins where there are none!

Hi Nick,
On Kimberlite the tank drains from the bottom. Is it different on the 54?

Thanks for the feedback. So the general consensus is that additional
polishing is not required as the Racor primary filter plus engine filter is
fine. So long as one takes the usual precautions. In addition whilst
motoring or running the generator some fuel polishing happens anyway.

This is nice to read.

I only raise this because the newer Amels have common rail turbo charged
engines, where fuel cleanliness is extra important. In addition we may well
be buying fuel with 20% biodiesel, and low sulphur. Biodiesel is more prone
to degrading and bacterial growth.
Amelia has been ashore for 5 months with brim full tank.
It is a shame there is no drain valve to remove a few litres off the bottom
of the tank.
