Abstract
A marine propulsion device comprises an internal combustion engine that has a piston-cylinder. A fuel injector injects fuel into the internal combustion engine. A fuel rail conveys the fuel to the fuel injector. The fuel rail has an upstream inlet end that receives the fuel and a downstream outlet end that supplies the fuel to the fuel injector. A fuel hose has an upstream inlet end that receives the fuel from a fuel reservoir and a downstream outlet end that discharges the fuel to the inlet end of the fuel rail. A filter element axially extends into at least one of the fuel rail and the fuel hose. The filter element is configured to filter particulate materials from the fuel.
