The Fuel gauge sender unit on my Bavaria Holiday 35 has corroded away and as cruising in Spain it is not practical for me to order from Bavaria, also i feel there must be other sources to obtain parts for yachts over 10yrs old, so if anybody can advise on where i could obtain a replacement i would be most grateful, unfortunately there is no part number on the present sender unit other than VDO 146 or 148 which is the maker, but i do not have their location or contact number
