The engine coughed and spluttered on startup but soon ran OK. We called in to Oxley Marine near the junction to have the fuel line and tank cleaned out. The water trap was dirty with grit but not the dreaded bug. Some had got to the fuel filter which stopped it there. A certain amount of dirty fuel was sucked out of the tank. Having replaced the filter and with fresh diesel in the tank the engine ran smoothly again.
I do not know where the grit or dirty fuel came from. Is there a case for the diesel suppliers to ensure clean fuel is put in our tanks. High turnover suppliers should be safer.
