In the FOA Handbook of Technical Tips 'Your Fisher' there is an article by Robert Chave (F30 'Tulip') which includes reference to his fuel cleaing system. He had installed a small (25 litre) day tank to supply the engine, which was continuously fed from the main tank through a filter - the overflow returning to the main tank. This appealled to me very much as any filter blockage left you with 25 litres of cleaned fuel to continue running, and must in addition have kept the main tank cleaner than on a normal installation. I would very much like to contact Robert Chave about this system, or anyone else who has tried this arrangement. Can anyone help? Geoff Butt
