page 3 Introduction How It Works Fuel from the tank enters the Diesel Pro body (suction side of the fuel system). Large contaminants and free water are separated from the fuel and remain in the body. Fuel rises into the clear cover. Contaminants and emulsified water are captured by the filter media. Fuel level rises to maintain a fuel path through the clean filter media and with lowest restriction. Clean, water-free fuel exits the Diesel Pro and flows to the lift pump. Seeing Is Believing See when NOT to change the fuel filter. See the condition of the fuel. Seeing what collects on the filter media or what s happening inside the clear cover can help diagnose many fuel and mechanical conditions. Filter on Top configuration. Water and debris removed from the fuel falls to the lower chamber and stays away from the filter media resulting in longer filter life. Built-in protection when priming the fuel filter. Unfiltered fuel is kept on the dirty side of the filter media during priming ensuring only clean fuel reaches the engine. Patented media. The Best in Class StrataPore media removes 95% of free and emulsified water. This performance far exceeds that of cellulose media. 1 2 3 4 Figure 1 - Seeing Is Believing 1. When new, the fuel level in the filter will be very low with minimal restriction. As the filter is used, contaminants collect on the filter from the bottom up. Fuel rises on the filter indicating remaining filter life. 2. Fuel level increases in clear cover. As contaminants collect on the filter, the fuel rises to a non-contaminated section of the filter, providing optimal filtration while maintaining lowest restriction. 3. Fuel level at filter wrap level. Even though the fuel level is now more than half of the filter element, the fuel is still flowing through clean media at minimal restriction levels. The filter still has significant life remaining. 4. The filter element is now completely covered by fuel. At this point, all of the media s surface area is utilized. Restriction is increasing and the filter element should be changed at the next scheduled maintenance interval.
page 4 Service Kit Installation This system must be installed between the fuel tank and the transfer fuel pump. If approved by the manufacturer, this system can be used as the only fuel filter in the fuel system by removing the existing filter and heads, or by removing the filters only and replacing them with special Diverter Caps (sold separately - see Table 1). Note: If the Diesel Pro is used as the primary filter and a secondary filter is required, secondary filter life may be extended. Diverter Cap Part Number Table 1 - Diverter Caps Required Filter Head Stud Size Required Filter Head Seal ID in (mm) Required Filter Head Seal OD in (mm) 3945182 S 1"-14 2.475 (62.865) 2.895 (73.533) 3945183 S 1"-14 3.225 (81.915) 3.435 (87.249) 3945184 S M16 x 1.5 2.475 (62.865) 2.895 (73.533) 3945185 S 3/4" x 16 2.475 (62.865) 2.895 (73.533) 3945186 S 7/8" x 14 2.475 (62.865) 2.895 (73.533) EEWARNING: When diesel fuel is circulated through an operating engine, it can become very hot. To prevent personal injury: EEScalding hazard! Do not allow heated liquid fuel to come in contact with eyes or unprotected skin. Always allow the engine and fuel to cool to ambient temperature before replacing the fuel filter or performing service operations which could result in the spillage of fuel from the fuel system. If this is not possible, protective clothing (face shield, insulated hat, gloves, apron) must be worn. EEFire hazard! Heated diesel fuel can form combustible vapor mixtures in the area around the fuel source. To eliminate the potential for fire, keep open flames, sparks or other potential ignition sources away from the work area, and do not smoke during filter replacement or service operations which could result in the escape of diesel fuel or fuel vapors. EEInhalation hazard! Always perform engine or vessel fuel system maintenance in a well ventilated area that is kept free of bystanders. EEThe ignition key must be in the OFF position. Installing the Diesel Pro Service Kit 1. With the engine shut down and at ambient temperature, close the fuel shutoff valve (if equipped) and place a suitable container under the fuel filters. 2. Remove the primary fuel filter element assembly, sedimenter, and/or water separator. Drain the used element and dispose of it in an environmentally responsible manner, according to state and/or federal (EPA) or national recommendations. The fuel can be returned to the tank. 3. For a one-filter system, select the required secondary filter head diverter cap from those listed in Table 1. The required part number is determined by the size of the spin-on filter stud and the filter sealing surface diameter. Install the diverter cap on the secondary filter head as follows: a. Remove the secondary fuel filter element, drain and dispose of it in an environmentally responsible manner according to government regulations (i.e., state/province, federal, etc.). The fuel can be returned to the tank. b. Lightly lubricate the seal on the top of the diverter cap with clean engine oil. c. Thread the adapter onto the secondary filter stud and tighten by hand only. d. Install the "Do Not Remove" sticker on the diverter cap. 4. Mount the Diesel Pro in the desired location using 3/8" (9.5 mm) Grade 8 hardware. Keep the following points in mind: a. Mounting the Diesel Pro directly on the engine is NOT RECOMMENDED. b. Mount vertically with the cover and element pointing up. c. Make sure there is enough top and side clearance for the cover to be conveniently removed for filter replacement (1.5" (38.1 mm) minimum). d. Bolt spacing is 5.25" (133.35 mm). E E CAUTION: The Diesel Pro MUST be installed so that the Filter Element is above the "FULL" level of the fuel tank. If mounted below full tank level, a shut off valve will be required at the inlet to allow filter changes without overflow of fuel.
page 5 5. Route the fuel supply line as follows (see Figure 2): a. Route the fuel supply line from the pickup on the fuel tank to the Diesel Pro inlet (labeled Fuel In ). b. Route the fuel outlet line from the Diesel Pro outlet (labeled Fuel Out ) to the inlet of the fuel pump. Diesel Pro b. Use 90 elbows only when necessary. c. If the fuel hoses are made up to length on the job, be sure that the inner liner of the fuel hose is not cut by the fitting, creating potential check valve effects. Also make sure hoses are clean and free of debris before installing. EECAUTION: To avoid damaging the aluminum fuel processor body, do not overtighten fuel lines or fuel line fittings. 7. If an electrical heater is required, see page 6, Installing an Optional Electric Heater.

Prime the Diesel Pro by filling the clear cover with clean diesel fuel until it reaches the top of the filter. 11. Install the vent cap. 12. Start the engine and run for one minute. Slowly open the vent cap and allow the fuel level to drop to about one inch above the collar. 13. Close the vent cap. Hand tighten only. Troubleshooting Every Diesel Pro is factory tested for leaks and is marked with a traceable number to show that it has passed production testing. Most field issues associated with leaks are related to loose fittings. These leaks are easily eliminated by checking and torquing the fuel fittings in the area of the leak. Some fittings may also require the application of liquid Teflon sealer. Note: All suction side fuel filters experience bubbles. It is normal to see champagne size bubbles in the Diesel Pro at the Diesel Pro outlet or at the lift pump. Check Valve Assembly Figure 11 Removing the Check Valve Assembly
page 10 Air Leak Air bubbles will be visible in the clear cover of the Diesel Pro if the leak originates from the fuel tank up to the fuel filter. The following is a quick test to isolate the air leak source. Bubbles Visible: 1. Remove the Diesel Pro inlet hose. 2. Install a jumper hose from the Diesel Pro to the fuel tank (through the fill cap) or to a container of fuel. 3. Start the engine. If this eliminates the air bubbles, the air source is at the fuel tank fittings or hose connections. 4. Tighten all fittings and connectors 5. Retest If air bubbles persist, the air source is on the Diesel Pro side of the system: 1. Tighten all fittings on the Diesel Pro. 2. Tighten the collar. 3. If the drain valve is suspected, install a plug in place of the drain valve (for test purposes only). If air bubbles continue to persist, test as follows: 1. Remove the Diesel Pro from the chassis. 2. Plug the fuel inlet port. Do not remove filter, cover/collar, vent cap, drain valve and/or check valve. If the Diesel Pro is equipped with a preheater, do not remove the preheater. 3. Apply 15 PSI of air pressure at the fuel outlet. Immerse the Diesel Pro in a tank of water and look for air bubbles. 4. Correct the source of the air leak and retest. Bubbles Not Visible Excessive Restriction If the fuel level is at the top of the filter, replace the fuel filter. The Diesel Pro will not cause excess system restriction if the fuel level is below the top of the filter. Loss of Prime When air is introduced into the fuel system, (for example, when draining water from the Diesel Pro or when replacing the fuel filter) a check valve is needed to keep the fuel system primed from the Diesel Pro back to the fuel tank. A check valve is standard with all Diesel Pros. To test for proper check valve operation: Remove the fuel inlet hose and open the vent cap. Fuel should not flow out of the Diesel Pro, although a slight seepage of fuel is normal. If fuel drains back to the fuel tank, remove the check valve assembly: 1. Disassemble the check valve assembly. Clean and inspect. 2. Replace the assembly if any cuts, grooves or nicks are evident in the valve or valve seat. 3. Reinstall the check valve assembly. 1. If there are symptoms of sucking air (indicated by engine loping/rough running performance/ power loss, etc.) and there are no bubbles in the clear cover, the air leak is either at the Diesel Pro outlet fitting, vent cap o-ring, the lift pump inlet connection, or the fuel hose/connections to the lift pump. 2. Inspect and tighten fittings as needed.
