  • Fuel filter gauge
    Patent number: 6289726
    Abstract: A fuel filter restriction indicating device communicating with the supply of fuel passing from a fuel tank to an internal combustion engine. The indicating device senses a decrease in the supply of fuel drawn through the fuel filter by the engine based upon changes in the amount of vacuum in the negative side of the fuel supply, the amount of restriction being indicated by the movement of an indicating device. A mechanism included in the indicating device senses the movement of the indicating device and progressively locks the indicating device into various indicating positions as the vacuum increases due to an increased restriction of the filter, so that the maximum reading of restriction achieved during engine operation remains visible to the operator or maintenance personnel even after the engine is turned off.
