A template for the mounting holes is provided in Illustration 8. Use the suggested bolts, nuts, and washers in order to attach the filter base. If necessary, use other appropriate hardware in order to attach the filter base. Attach the filter base to the machine or to the mounting bracket. Refer to Table 1 for the parts list.The mounting location for the fuel/water separator will be determined by the application. Ensure that the fuel/water separator is located in an area that can be easily serviced. Ensure that the fuel/water separator is located away from electrical components. Ensure that the fuel/water separator is located away from debris and all hot surfaces.The diameter of the fuel hose will be determined by the application and by the size of the fuel line from the fuel tank. The size of the fuel fittings will be determined by the application. The fuel hose should have a minimum rating of 2100 kPa (300 psi). The fuel hose must be routed away from electrical components and away from hot surfaces. The fuel hose must be routed away from rubbing and away from chafing surfaces.Typical Diagram of Plumbing for a Single Filter Group

This illustration is effective with all of the engine models that are smaller than the 3512 Engines. Typical Diagram of Plumbing for Multiple Single Filter Groups
Illustration 4 g00995148
This illustration is effective with all of the 3512 Engines and up.Note: Connect the fuel/water separators in parallel when two or more fuel/water separators are used. Connecting the fuel/water separators in parallel will require two additional tee fittings. The size of these fittings will be determined by the application and by the size of the fuel line from the fuel tank.For parallel connections, use one tee to split the fuel line from the fuel tank and divide the flow between both of the single filter groups. Use another tee to recombine the outlet lines from the individual filters before the lines reach the fuel pump.This may also require some additional hardware that is not mentioned, including straight fittings and/or elbow fittings. These fittings will be determined by the following factors: the application and the size of the fuel line that is required by the fuel pump.Typical Profile of Installation for 225-6404 Base As
