The Multiquip EE40863 Fuel System Assembly Sub Base UL142 50 Gal is a genuine OEM assembly designed for UL142-rated sub base fuel tank configurations. As a factory-sourced replacement, this assembly is built to the same specifications as the original unit, ensuring a direct swap with no guesswork on fit or function. Sourced directly through Multiquip's authorized parts network, the part is the correct component for maintaining compliant, safe fuel system operation on UL142 equipment. Confirm your model code against UL142 fitment before ordering to ensure compatibility.
Key Features
- Genuine OEM Assembly — Manufactured to Multiquip's original design standards, ensuring every component within the fuel system sub assembly meets the same construction quality as the part it replaces.
- UL142 Compliance Built In — This assembly is specifically engineered for UL142-rated sub base fuel tank systems, supporting the listed safety and containment requirements associated with that standard.
- 50-Gallon Sub Base Configuration — Sized and configured for 50-gallon sub base applications, matching the original tank capacity and fuel system layout without adaptation.
- Complete Fuel System Sub Assembly — Supplied as a ready-to-install assembly rather than individual components, simplifying service and reducing the risk of mismatched parts during a repair.
- Fuel System Integrity — A correctly functioning fuel system assembly maintains consistent fuel delivery and containment; a worn or failed unit can compromise fuel supply, create leak risks, and take equipment out of service.
- Fits UL142 Series Equipment — Confirmed fitment for UL142 sub base generator and power equipment configurations; reference model code UL142 when verifying compatibility.
The fuel system sub base assembly is the integrated fuel delivery and containment unit mounted beneath the generator or power equipment set. It stores, supplies, and manages fuel flow from the sub base tank to the engine, while the UL142 rating confirms the tank construction meets recognized standards for aboveground flammable and combustible liquid storage. When this assembly degrades — through corrosion, seal failure, or component wear — fuel delivery becomes unreliable and containment integrity is compromised, creating both operational and safety concerns. Replacing it with a genuine OEM assembly like the part restores the system to its original specification and maintains the equipment's rated compliance.
