3 SYSTEM OVERVIEW Welcome to the AirDog Fuel Preporator Fuel Air Separation System for Class 8 Trucks The AirDog, with ADVANCED FUEL AIR SEPARATION, DEMAND FLOW, ADJUSTABLE REGULATOR, LOW PRESSURE SWITCH with LED INDICATOR and the NEW 4G-HD FUEL PUMP, is a premium fuel filtration and delivery system for the Volvo VED-12 & D13 Diesel Engine. Air & Vapor are compressible! When Air/Vapor is present in a fuel injection system the pressure buildup and injection of fuel is delayed while the Air/Vapor is being compressed. This delay retards the injection timing causing a shorter power stroke and low power, increased fuel consumption and increased exhaust emissions. Preventing the formation of vapor from pump cavitation and removing entrained air from the fuel flow to the injectors restores Correct Injection Timing. Diesel engines equipped with the AirDog can now perform as designed, delivering test cell performance while in real world use! The AirDog removes water, particulates and most importantly, the air that becomes entrained in diesel fuel, from the fuel flow to your engine. The entrained air and vapor that is separated from the fuel is returned to the fuel tank through a small return line. The fuel flow to the engine s transfer pump is at a NET POSITIVE PRESSURE HEAD preventing cavitation and the formation of vapor thus overcoming the performance related problems from plugged fuel filters, high altitude operation and torque loss at higher engine RPM s. All AirDog products are manufactured with a personal touch, unsurpassed attention to detail and the most stringent quality assurance!

7 Section 4 Selecting the Best Mounting Location Selecting the Best Location to Mount the AirDog Installing the AirDog at the proper location on the vehicle is most important. When deciding where to locate the AirDog, the following points should be considered: Best relationship to the transfer pump and the original primary fuel filter location. Protection from the elements and road debris. Accessibility for service. CAUTION: DO NOT mount the AirDog directly on the engine. Mounting the AirDog directly on the engine will immediately void your AirDog Warranty! The Volvo primary fuel filter is usually found on earlier model trucks mounted on the passenger side frame rail, just to the rear of the bumper brackets. Additionally, Volvo uses plastic type fuel lines and plastic quick connect fittings. Figure 2 Figure 3 The AirDog can be easily mounted in the same location as the OE primary fuel filter in this application, as shown in Figure 3. Figure 4 On later model Volvo trucks, such as this 2006 (fig. 4), the primary filter may be found on the driver s side. Figure 5 Figure 5 shows the AirDog mounted on the original filter bracket. The bracket was reversed to do this. See Universal Sandwich Mounting Bracket Guide on Next Page 7

11 Section 6 Pressure Sensor Switch and Fuel Fittings Pressure Sensor & Fuel Fittings IMPORTANT: Use diesel compatible thread sealer when installing NPT fittings Remove the 1/8 NPT plug located in the end of the 45 elbow. Install the pressure sensor switch into the elbow. Figure 16 Figure Install the #6 JIC x ¼ NPT Air/Vapor return fitting in the AirDog port marked TANK Install the Quick connect x ½ NPT fitting removed from the original primary filter in the port marked ENGINE. Figure 19 Figure If your installation places the AirDog on the passenger side as seen in Fig. 13, use the 90º ½ Male NPT x ½ Female NPT fitting and the Quick Connect x ½ NPT fitting to connect the fuel supply line. FUEL LINE OVERVIEW The AirDog has been engineered to eliminate fuel related problems. It is important that the fuel lines are assembled and installed properly so as not to cause fuel flow restriction. When possible, use the fuel lines that are on the vehicle. This will reduce your installation costs and make the installation go much more quickly. NOTE: On various class 8 trucks, the manufacturer may use plastic or other than traditional steel braid fuel lines. These lines require special fittings. The fittings used with the original primary fuel filter are specific to the fuel lines used on the truck. When possible, mount the AirDog in the location that will allow the use of the original fuel lines and fittings. Fuel Supply Line: The fuel supply lines from the tank to the AirDog and to the engine should be size 10 or, at the absolute minimum, size 8 (1/2 ID). Air/Vapor Return Line: The AirDog Air/Vapor return line can be connected to the engine s return line. A size 6 is adequate for the Air/Vapor return line. Primary Fuel Filters: It is most important that there are no fuel filters between the fuel tank and the AirDog or between the AirDog and the engine s transfer pump to plug and cause restriction. These filters should be removed from the system as part of the AirDog installation. Secondary Fuel Filters: DO NOT REMOVE SECONDARY FUEL FILTERS. This is the filter between the transfer pump and the engine. 11

12 Section 7 Fuel Lines Section 7A: Installing the AirDog Air/Vapor Return Line. The AirDog, with DEMAND FLOW, returns entrained air & vapor (foam) with very little fuel to the tank. With these features, the AirDog air/vapor return line can be connected directly to the engine return line. NOTE: For your convenience, 7 feet of #6 line and fittings are included. 7A-1. In the example depicted in figure 20, install the 16mm AirDog return T & O ring on the fuel return line. Attach the Quick Connect 16mm female fitting to the return fitting. Re-attach the original fuel return line. Figure 21 Figure 20 7A-2. Measure and cut the length of #6 fuel line required to connect the AirDog Air/Vapor return port (A) to the new return T (B) installed on the secondary fuel filter head. Assemble and install the fuel line per standard procedures, connecting it to the relative fuel fittings. For Trucks with only one fuel tank, it may be easier to run the Air/Vapor Return Line directly to the tank. CAUTION: Do not connect the AirDog return line to one tank on a two tank system! 7A-3. Remove the plug from an extra port. In some cases, it may be necessary to drill and tap a port. Figure 22 Figure 23 7A-4. Install the NPT x #6 JIC Flare fitting into the port. 12 Figure 24

17 Section 9 Initial Startup SECTION 9: INITIAL START UP PROCEDURE The AirDog is a self priming system. However, to prevent damage to a dry seal and reduce the life expectancy of the system, it is suggested to pre-fill the water separator/pre-filter with diesel fuel to the bottom of the NUT PLATE. r 9-1. Pre-fill the water separator/pre-filter with diesel fuel up to the bottom of the nut plate. r 9-2. Turn the starter key to the on/run position. r 9-3. The AirDog should now be running and pumping fuel, bleed the fuel line to the engine by loosening the fuel line connection at the engine fitting. As soon as the line is purged of air, tighten the fuel fitting. NOTE: Put a rag or shop towel around the fitting to prevent fuel splatter or spray. Catch all spilled fuel and dispose of properly. RECHECK ALL FUEL FITTINGS FOR LEAKS. BE SURE ALL LINES ARE PROPERLY SECURED TO PROTECT FROM CHAFFING AND ABRASION. RECHECK ALL ELECTRICAL LINES, SECURE AS NECESSARY. r 9-4. Start your engine! VERY IMPORTANT: Should pressure flow to the engine drop below minimum requirements, the AMBER LED light will immediately illuminate. First check the water separator. Then, check the screen in the water separator nipple. Clean or replace as necessary. 17

18 Section 10 Fuel Filter & Pre-Filter Servicing the AirDog Fuel Filter and Water Separator/Prefilter The AirDog low pressure switch monitors the fuel filter and water separator! FUEL FILTER: Plugging of the fuel filter will cause the AirDog Indicator Light to illuminate. Replace the fuel filter as necessary! Typically our fuel filters are good for a 40,000 mile service period because they are micro glass media instead of typical paper. It is recommended to replace the fuel filter at 40,000 miles of service OR when the AMBER Indicator Light illuminates, which ever comes first! When replacing the fuel filter, be sure to clean the under side of the AirDog base. It is not necessary to pre-fill the fuel filter with fuel, the AirDog will fill the filter and prime the system automatically. Follow the instructions on the filter for proper tightening procedures. AirDog Fuel Filter Pre-filter Nipple with Wire Screen (1 1/8th Inch Hex) Figure 46 Prefilter/Water Separator With Drain Valve The Water Separator/Pre-filter WATER SEPARATOR: Should the water separator/pre-filter or the wire screen in the nipple become plugged, preventing sufficient operating pressure flow to the engine, the Amber Indicator Light will immediately illuminate Check the water separator/pre-filter for plugging. Clean or Replace as necessary! If the light continues to be on, check the screen in the water separator/pre-filter nipple for debris and plugging. Clean as necessary! Replace the water separator if it becomes damaged or permanently plugged. Servicing of the water separator simply requires draining at regular intervals. It is suggested to check/drain the water separator weekly or as needed should you experience excessive water in fuel conditions. Before re-installing the water separator after cleaning, be sure to clean the under side of the AirDog base. Follow the instructions printed on the water separator/pre-filter for proper tightening procedures. DO NOT over tighten and damage the water separator with a filter wrench. Caution: Be careful to prevent any contaminates or debris from entering the water separator when remove it for cleaning! Even though the water separator/pre-filter nipple has a protective wire screen, debris could jam the Gerotor and cause the fuse to blow. This is not a warranty item. Dispose of waste fuel and used filters properly to protect OUR environment! 18
