Positioning The Assembly

Filter assemblies should be installed on vacuum side of fuel transfer pump for optimum water separating efficiency. See Installation Diagram.
Keep fuel line restrictions to a minimum. Locate the 500FG filter assembly between horizontal planes of bottom of fuel tank and inlet of fuel pump, if possible. If 500FG filter assembly is installed in an application where the fuel tank is higher than the filter, a shut-off valve must be installed between the tank and 500FG filter assembly INLET. This will be used when servicing the replacement filter.

Before Installing The Assembly

• Obtain good ventilation and lighting.
• Maintain a safe working environment.
• Engine must be off for installation.
• DO NOT smoke or allow open flames near installation.

Installing The Filter

Completely remove any vacuum side filters in fuel line between fuel tank and fuel pump. This is where the Racor filter will mount. Leaving these filters in place will add to fuel line restriction. Filter heads cast into engine or that are non-removable or hard piped should be serviced with a new filter and left in place.
Keep fuel flow restriction to a minimum. Always use the maximum size fuel hose possible. Do not make sharp bends with flexible hose as kinks may occur. Avoid use of two 45° elbow fittings where one 90° elbow will work. When routing hose, avoid surfaces that move, have sharp edges, or get hot (such as exhaust piping).
