2 Large contaminants and free water are separated from the fuel and remain in the body. Fuel rises into the clear cover. Contaminants and emulsifi ed water are captured by the fi lter media. Fuel level rises to maintain a fuel path through the clean fi lter media with low restriction. Clean, water-free fuel exits the Fuel Processor and fl ows to the engine fuel injection PRO 382 TECHNICAL MANUAL1 Technology, LLCDAVCO Technology, LLC P. O.

3 See the condition of the fuel. Seeing what collects on the fi lter media or what s happening inside the clear cover can help diagnose many fuel and mechanical conditions. Filter on Top confi guration. Water and debris removed from the fuel falls to the lower chamber and stays away from the fi lter media resulting in longer fi lter life. Built in protection when priming the fuel fi lter. Unfi ltered fuel is kept on the dirty side of the fi lter media during priming ensuring only clean fuel reaches the engine. Patented media.

4 The Best in Class StrataPore media removes 98% of free and emulsifi ed water over the life of the fi lter. This far exceeds the performance of cellulose media. SEEING IS BELIEVING When new, the fuel level in the fi lter will be very low with minimal restriction. As the fi lter is used, contaminants collect on the fi lter from the bottom up. Fuel rises on the fi lter indicating remaining fi lter level increases in clear cover. As contaminants collect on the fi lter, the fuel rises to a non-contami-nated section of the fi lter, providing optimal fi ltration while maintaining lowest level at fi lter wrap level.

5 Even though the fuel level is now more than half of the fi lter element, the fuel is still fl owing through clean media at minimal restriction levels. The fi lter still has signifi cant life fi lter element is now completely covered by fuel. At this point, all of the media s surface area is utilized. Restriction is increasing and the fi lter element should be changed at the next scheduled mainte-nance PRO 382 TECHNICAL MANUAL2 Technology, LLCDAVCO Technology, LLC P. O. Box 487 Saline, MI 48176 Call 800-328-2611 f1271 Updated 08/29/2011 IMPORTANT SAFETY PRECAUTIONSWARNING: When diesel fuel is circulated through an operating engine, it can become very hot.

6 To prevent personal injury: Scalding hazard! Do not allow fuel to come in contact with eyes or unprotected skin. Allow the engine and fuel to cool to ambient temperature before replacing the fuel fi lter or performing service operations which could result in spillage of fuel from the fuel system. If this is not possible, protective equipment (face shield, insulated hat, gloves, and apron) must be worn. Fire Prevention! Heated diesel fuel can form combustible vapor mixtures in the area around the fuel source. To eliminate the potential for fi re, keep open fl ames, sparks or other potential ignition sources away from the work area.

7 Do not smoke during fi lter replacement or service operations. Inhalation Prevention! Always perform engine or vehicle fuel system maintenance in a well ventilated area that is kept free of bystanders. The ignition key must be in the off PRO 382 TECHNICAL MANUAL3 Technology, LLCDAVCO Technology, LLC P. O.

In some cases, the Fuel Pro can be used as the only fuel fi lter in the system. This is generally dependent on the engine model year. Consult the engine manufacturer for their recommendation.

9 If the Fuel Pro can be used as a single fi lter, DAVCO offers a diverter cap to replace the secondary fi lter. (See diverter cap installation section)Mounting the Fuel ProMount the Fuel Pro keeping the following points in mind: Do not install the Fuel Pro directly on the engine. Mount vertically with the cover and element pointing up. Make sure there is enough top and side clearance for the cover to be conveniently removed for fi lter replace-ment. The Fuel Pro MUST be installed so that the Filter Ele-ment is above the "FULL" level of the fuel 1: With the engine shut down and at ambient temper-ature, close the fuel shutoff valve (if equipped) and place a suitable container under the fuel fi 2: Remove the primary fuel fi lter element assembly, sedimenter, and/or water separator.

10 Drain the used ele-ment and dispose of it in an environmentally responsible manner, according to state and/or federal (EPA) Line RoutingTo minimize fuel system restriction, observe the follow-ing guidelines when plumbing the fuel system: Keep the fuel line routing as smooth as possible with no low-hanging loops which can trap water. Use 90 elbows only when necessary. If the fuel hoses are cut to length on the job, be sure that the inner liner of the fuel hose is not cut by the fi tting, which can cause check valve performance issues.
