LINES GP-FUEL FILTER 4562656 - Caterpillar

Operation of the Vokes Fuel Filter
The filter may be operated with the fuel flow through one side of the filter or through both sides of the filter. Either practice is acceptable, provided that the maximum fuel filter differential pressure is not exceeded. Operating with the fuel flow through one side of the filter is recommended.Operating With One Side of the Filter
Caterpillar recommends operating with the fuel flow through one side of the filter during normal operation. This practice enables the filter elements to be replaced without shutting down the engine. When the maximum fuel filter differential pressure is reached, redirect the fuel flow through the new filter element. The dirty element may then be replaced during operation. The new replacement element is ready for use when the next element is replaced.Operating With Both Sides of the Filter
When both sides of the filter are active, each element filters 50 percent of the fuel flow. This increases the time between replacement of the elements. However, this practice may require the engine to be shut down in order to replace the elements. This may be suitable for intermittent operation, but not for continuous operation.During operation, the fuel flow must be directed through one side of the filter in order to replace an element. To avoid exceeding the maximum fuel filter differential pressure during operation, the element must be replaced before the element has reached the maximum pressure. To achieve optimum use of the filter elements, direct the fuel flow through one side of the filter.Replacing the Filter Element During Engine Operation
Filter contains hot pressurized fluid when engine is running.Follow instructions on control valve to avoid personal injury.If rapid air movement exists to blow fluid, Stop the engine to avoid fire.
