An electric oil drain pump makes essential oil changes considerably easier. The pump is permanently installed, thus eliminating the dirt and inconvenience of manually draining the sump. The pump is self-priming and is also suitable for flushing and as a bilge pump.
Separately mounted oil filters can be used for engine installations where the side-mounted standard filter is not easily accessible, e.g. in narrow engine rooms or for twin installations. The filter is then mounted on the exhaust riser.
