Racor Fuel Filtration provides the highest quality filtration for the removal of contaminate, water or air from your fuel system.  Solid and Semi Solid Contamination such as rust, sand, and other small particles routinely find their way into diesel fuel.  Sometimes larger identiable objects such as pebbles, leaves and paint chips are also present.  The most common culprit of plugged fuel filter elements are oxidized organic semi-solid contaminants such as gums, varnishes and carbon.  To be effectiv, fuel filtration devices must provide adequate solid particle retention efficiencies while also maintaining large capacities for the natural organic contaminants found in diesel fuel.  Water, an Engine's Worst Enemy - water causes iron components to rust, forming loose aggregated particles of iron oxide contributing to injector wear.  At the interface of water and diesel fuel, microbiological growth rapidly occurs under ideal conditions.  The microbes form a sluge that can actually hinder filter effectiveness and injector performance.  Water inhaled by the injection system can displace lubrication provided by the fuel oil itself, causing galling and premature wear.  Typical primary filtration devices do not have the capability to remove water, leaving the engine prey to pump and injector damage and reduced efficiency.  It is therefore essential to efectively seeparate water from the fuel prior to the final stages of solid particulate filtration.
