Fuel Pump Adapter With Indexed Port Conversion and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional in-tank fuel pumps have specific connections that are not compatible with alternate port types, such as o-ring AN-ports, limiting the ability to easily change connection types and utilize existing fuel pumps with different fuel pickup systems.
Innovation Solution
A pump adapter that slides onto the existing fuel pump, providing indexing for proper alignment and sealing, allowing connection of alternate port types and enabling additional fuel delivery or filtration components, with features like a clamp and weep hole for secure and fluid-tight connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional fuel pump with a specific connection type is used, then the pump can maintain its original connection integrity, but it cannot be easily adapted to alternate port types such as o-ring AN-ports
Solution Approach 1:
An adapter is introduced as an intermediary component between the traditional fuel pump and the alternate port type. The adapter has a first end that connects to the existing fuel pump connection and a second end that provides the alternate port type (such as o-ring AN-port), enabling compatibility without modifying the original pump
Solution Approach 2:
The adapter is designed to provide multiple connection type options, allowing a single adapter component to support various port types (e.g., o-ring AN-ports, other fittings). This multi-functionality enables the same adapter to work with different connection standards, increasing system versatility
2Adaptability or versatility
If an adapter is added to convert connection types, then compatibility with alternate port types is achieved, but the device complexity increases
Solution Approach 1:
The adapter integrates multiple functions into a single component: it provides connection adaptation, includes indexing features for alignment, incorporates sealing mechanisms, and offers mounting provisions for additional components. By merging these functions into one adapter unit, the overall system complexity is minimized despite the added adaptability
3Reliability
If indexing features are added for proper alignment, then sealing and fuel communication are ensured, but the manufacturing complexity increases
Solution Approach 1:
Indexing features such as asymmetric protrusions or keyways are incorporated into the adapter design to ensure proper rotational alignment with the fuel pump. These asymmetric elements provide unique positioning that guarantees correct orientation for sealing surfaces and fuel flow paths, reliability without complex adjustment mechanisms

AI summary
The present embodiments provide an adapter which may be utilized with traditional in-tank fuel pumps to convert the pump from a first style to a second, alternative style. The instant embodiment utilizes an adapter which slides on the end of an existing fuel pump type and provides indexing for proper alignment and fuel communication. The adapter also allows connection of alternate type of port or fitting in order to allow connection with more desirable type of fuel pickup system. The adapter is then clamped onto the end of the pump once the adapter and pump are indexed to proper alignment for sealing and fuel communication. The adapter may also include a coupling for a fitting to connect additional fuel delivery and/or filtration parts to the pump.
