Abstract: A system and method for manufacture of the system are provided. In one example, the system comprises a first component, a second component securing the first component to a portion of the system, and a flexible strip with an abrasion resistant coating including a copolymer. The first component or the second component includes a corrosion coating on an exterior surface and the flexible strip is interposed between a surface of the first or second component and the corrosion coating.

Abstract: Systems and methods are presented herein for detecting a degradation condition in a variable volume device of a fuel tank of a vehicle. In one example, the issues described above may be addressed by a diagnostic method for a vehicle with a valve and a fuel tank having a variable volume device internal to the tank, comprising: operating the fuel tank over a diurnal cycle; and differentiating between degradation of the fuel tank and the variable volume device based on a fuel tank pressure at a plurality of different valve conditions; and indicating the differentiated degradation.

Abstract: Methods and systems are provided for diagnosing leaks in a fuel system. In one example, a method may include monitoring a fuel level in a vehicle fuel tank of the fuel system during refueling and indicating degradation of the vehicle fuel tank and/or a bellows coupled to the vehicle fuel tank based on the monitored fuel level. In some examples, indicating the degradation may further be based on a rate of fuel supplied to the vehicle fuel tank during the refueling and/or a vehicle fuel economy. In this way, degradation to the vehicle fuel tank and the bellows may be passively determined with minimal specialized components in the fuel system.

Abstract: Methods and systems are provided for a reservoir including a ratcheting support column. In one example, a support column for a reservoir includes a first portion and a second portion configured to move toward each other when pressed together. The first portion and second portion do not move away from each other when they are urged in opposite directions.

Abstract: A fuel tank is provided. The fuel tank includes a housing enclosing a fuel, the housing including a reinforcement region having two opposing interior surfaces in face sharing contact with one another and a mechanical fastener extending through the reinforcement region, the mechanical fastener including a first head positioned within an external depression of the reinforcement region.

Abstract: A fuel tank having one or more support domes configured to engage with, and assist in positioning, a fuel tank insert.

Abstract: A distensible fuel tank included in a vehicle, comprising a housing and a compliance structure coupled to the housing, the compliance structure including a support element coupled to a first side of a structural element and a reinforcing element coupled to a second opposing side of the structural element.

Abstract: A system for diffusing a fuel flow for a vehicle. The system includes a fuel tank, containing fuel in both liquid and vapor form. A fuel filler spud extends from a fuel inlet on the exterior of the vehicle into the fuel tank and defines a fuel outlet there. A diffuser is mounted on the fuel filler spud for diffusing fuel flowing into the tank. The diffuser can take the form of a tongue-like protrusion, which can have flow channels or grooves, as well as flow diverters, which can be arranged in a matrix in the fuel outlet.

Abstract: A distensible fuel tank included in a vehicle is provided. The distensible fuel tank includes a housing and a compliance structure coupled to the housing, the compliance structure including a base element coupled to a side of a structural element.
