A first class fuel system contains a primary and a secondary fuel filter. The secondary filter on the engine is
Standard with each Craftsman Marine engine, but the primary filter - preferably incorporating a water
Separator - is often positioned into the fuel system as an extra. When this filter is not fitted, the secondary
Filter on the engine will be clogged up much sooner. Also, the proper functioning of the fuel lift pump can
Be impeded by even small particles of dirt in the fuel.
Replace the filters in accordance with the prescribed service intervals. The cost of a filter is next to nothing,
Compared with the inconvenience of a stalled engine and the possible danger it entails.
