Problems solved by technology
Sometimes it may be difficult to determine the cause of a malfunction or poorer-than-expected operation
Therefore, it may be difficult to determine whether the cause is within the component itself, within related components, or due to conditions beyond the conditions for which the component was originally designed
For example, if a component is subjected to higher than expected temperatures, pressures, power supplies, etc., failure or reduced performance of the component may not be indicative of any problem with the component itself

Embodiment Construction
[0015] More specifically, refer to the accompanying drawings. figure 1 and 5 -7 illustrate the components of the vehicle fuel system, including, for example, a fuel tank 10, a fuel pump 12, and a fuel liquid surface sensor 14. The fuel tank 10 includes an internal volume 15 in which a liquid fuel can be stored. The fuel pump 12 can be an electric motor driven pump that is inhaled from the fuel tank 10 to pressurize the fuel and transmit fuel to the engine under pressure. Fuel liquid surface sensor 14 can include variable resistance circuit 16 ( Figure 7 ) Provides an indication of a fuel liquid in the fuel tank 10.
[0016] These and other fuel system components may undergo changes in the vehicle, which may affect their performance, durability and reliability. For example, in addition to other possible changes and things, components may have different temperatures, pressure, power supply, and fuel types. Sometimes, components may experience one or more conditions that exceed them ...

The present invention relates to indication of threshold conditions within a vehicle fuel system. The fuel system component may include a body arranged for storing or moving fuel within the fuel system, and an indicator associated with the body to provide an indication when the body experiences a condition outside a threshold. Indicators may be responsive to environmental or system conditions outside one or more thresholds. For example, without limitation, an indicator may be responsive to one or more of temperature, pressure, corrosion, and electrical conditions to provide an indication when at least one condition exceeds a threshold for that condition.
Description
Technical field [0001] The present disclosure generally relates to a vehicle fuel system and more particularly to an indication of one or more threshold conditions in the vehicle fuel system component. Background technique [0002] The vehicle fuel system includes a number of components that are exposed to various environmental and operating conditions. In use, some fuel system components may fail or do not work as expected. Sometimes it may be difficult to determine the failure or the cause of the expected operation. Therefore, it may be difficult to determine whether the part is in the part belongs within the related components, due to the conditions that exceed the conditions that the part is originally designed for use. For example, if the component is subjected to a higher temperature, pressure, power supply, such as expected temperature, pressure, power supply, etc., the failure or decreased performance of the component may not indicate any problems in the part itself. Inv...
