Abstract: A fuel cap is described as having a top assembly and a bottom assembly slidably engaged with, and concentric to, the top assembly. The top assembly having a cap cover and a cylindrical cap body concentric with and protruding substantially perpendicularly from, an underside surface of the cap cover. The bottom assembly having a vacuum valve operatively coupled with a valve body. A wire-form keeper may slidably secure the bottom assembly to the top assembly. A pressure spring may impart a force that biases said bottom assembly away from said top assembly.

Abstract: Disclosed herein is a system and method for reporting fuel quality or fuel equipment status, more specifically, systems and methods for detecting and reporting quality, contaminates, cleanliness, and/or free or emulsified water in fuel, as well as the status of a fuel dispenser or dispensing fuel filter. The fuel quality or fuel equipment status may be reported in real time, or near real time, to a remote device or system for further analysis.

Abstract: A fuel filter comprises a filter housing having a fuel inlet and a fuel outlet, and a laminate positioned within said filter housing, the laminate comprising a first layer and a second layer having methyl hydroxyethyl cellulose between said first layer and said second layer, wherein the fuel filter is configured to direct fuel received at the fuel inlet to the fuel outlet through the laminate.

Abstract: A fuel filter comprises a filter housing, a filter assembly positioned within said filter housing, a fuel inlet adapted to receive fuel into the filter housing, and a fuel outlet. The filter assembly may have a first end cap, a second end cap, and a filter element positioned therebetween. The filter element may comprise a particulate filter component and a water sensing component, the water sensing component having a center tube, a water sensing layer, and a screen. The water sensing layer may wrap around at least a portion of the center tube and be secured in place by the screen. The water sensing layer comprises a gelling and thickening agent, such as methyl hydroxyethyl cellulose. In operation, the fuel filter is configured to direct fuel received at the fuel inlet to the fuel outlet by way of the water sensing component and the particulate filter component.
