Commonly the most overlooked component in a fuel system, filter neglect can be the most costly. If not cleaned or replaced regularly, filter elements can become clogged resulting in reduced fuel flow, engine performance and ultimately, fuel pump or even worse, engine damage. By simply replacing and/or cleaning your filter elements regularly, you can avoid costly repairs to your fuel system and ensure peak engine performance. Severe duty applications or newly installed systems may require more frequent maintenance. How do you know what element you need for your filter? Several Aeromotive filters share the same housing, but the elements inside may be drastically different and putting the wrong filter or element in the wrong place could be costly for your fuel pump or your engine. To find out, look inside the inlet of the filter. Stamped on the top of the element is the micron rating. This will tell you what element you need for your filter.
