Cezanne's blocked Aorta...

About a week ago, when we were on the Saone R. Cezanne had a problem. His Aorta became blocked  & he finally died.(fungus in the fuel tank blocked the outlets etc.) We were lucky that we were nearing a jetty beside a big lock, so we tied up & after much time trying to rectify the problem  & cleaning out some pipes, still no go, so Barry decided to use the foot pump which we have for the bikes. It has a special fitting , just the right size to fit into te diesel tank. A few pumps & voila, air flowed through & cezanne sprang to life.  The fuel filter was needing to be changed regularly, so we were a little concerned about being on the Rhone. There is a boat workshop at Pont de Vaux, so we had them do a temporary repair until we get to our winter mooring.This involved putting in another small tank & bypassing the old one[cezanne's bypass!] which was over 1/2 full, with the return, we were told, would be minimal & not a problem.  There was a lot of rain overnight. This 5km long R. was running high.The pontoon which I had to step onto to go ashore, to press a button to start the automtic lock, was under water. 2km down the Saone, Barry looked at the fuel guage Which was reading much higher than when we left.A few calculations told us we would not reach Macon, so about turn & with some hurried changing over of fuel etc & then a stop to do some more changes we arrived back here. The mechanic came & did some more alterations, so as the weather will be much better tomorrow we have decided to stay here another day.
