32 33ENGINE ACCESSORIES ENGINE ACCESSORIES – FUEL SUPPLY
Volvo Penta engines are recognized all over the world as technically 
sophisticated and reliable marine engines.
Every accessory is a part in a system. They are all designed and 
developed to work together. All accessories fulfill our tough de-
mands of durability and reliability. They are tailor made designed 
for easy mounting to engine and drive, eliminating complicated 
adaptations and tested as carefully as the engine. 
Fuel supply
A reliable supply of clean fuel to the engine. Nothing is more 
important for reliability and safety at sea.
Fuel filter/water separator, diesel engines
Fuel filter/water separator for small diesel engines. The filter is intend-
ed for installation between the fuel tank and the engine. In the lower 
container/sight glass, it is easy to detect whether or not water or other 
impurities have accumulated. The filter is supplied without connection 
parts for the fuel lines (see “Fuel line fittings”).

Water in Fuel Alarm
To get an early warning for water in the fuel tank the best position for 
a water sensor is in the Fuel Filter/Water separator between the tank 
and the engine. The sensor will detect water in the bowl of the water 
separator and give the early warning wanted.
