Fuel Polishing

ngtnewington Newington

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.
