When replacing your filter remember gasoline is a very highly flammable substance. Make sure the engine to your device is turned off, the engine and surrounding components are cool to the touch, and you have the necessary fire suppression equipment nearby in case there are any mishaps. Keep heat, sparks, and flame away from the filter and clean up any spills immediately.
CFS’s units are produced with a 10-micron filter and are not suitable for use as a suction side filter with electric fuel pumps and carbureted systems. This application requires an 80- to 100-micron screen. Use of a 10-micron filter causes cavitation in the pump, leading to premature failure of the pump. Also, filters are not designed to separate oil from gas in blended fuel mixtures. Do not use them in these applications.
In marine applications, CFS’s products are not to be used in the engine compartment. CFS’s products include a clear acrylic plastic bowl, and these materials are not certified for in-compartment applications. You should only use products with a metal drain bowl in these applications.
Element replacement should be after every 100 hours of use, or when there is a noticeable power loss, whichever comes first. Note, it is highly recommended to carry an extra replacement element in case the need to replace the filter arises unexpectedly.
