Multiquip EE45515 Sub-Base Double Wall Tank UL142 36Hr 400 G

The Multiquip EE45515 Sub-Base Double Wall Tank UL142 36Hr 400 G is a genuine OEM fuel containment tank designed for UL142 series equipment. This 400-gallon, double-wall sub-base tank is built to UL142 standards, providing a structurally integrated fuel storage solution rated for up to 36 hours of runtime. As a genuine Multiquip OEM component, EE45515 is manufactured to the exact specifications required for proper fit and function on compatible UL142 configurations. Sourced direct through DHS Equipment, this tank ships as the factory-authorized replacement for your generator or power system installation.

Key Features

• UL142 Certified Double-Wall Construction — Built to Underwriters Laboratories UL142 standards for aboveground flammable liquid storage, meeting containment and leak-prevention requirements demanded by code-compliant installations.
• 400-Gallon Capacity with 36-Hour Runtime Rating — Sized to support extended-run power generation applications, reducing the frequency of refueling interventions during critical or continuous-duty operations.
• Genuine OEM Component — Manufactured to Multiquip's original design specifications, ensuring the tank dimensions, mounting footprint, and connection points align exactly with UL142 series equipment without secondary modifications.
• Integrated Sub-Base Design — Functions as the structural base for the generator set while simultaneously housing the fuel supply, keeping the installation footprint compact and the fuel system self-contained.
• Fuel System Safety Compliance — Double-wall design provides secondary containment, a key requirement for meeting environmental and fire-safety regulations governing stationary generator fuel systems on commercial and industrial sites.

A sub-base double-wall tank serves two purposes simultaneously: it acts as the structural mounting base for the generator set sitting above it, and it houses the primary fuel supply within a UL142-certified double-wall enclosure. The inner wall holds the fuel, while the outer wall provides secondary containment — capturing any leak before it reaches the surrounding environment. This design is a code requirement in many jurisdictions for stationary power systems. When a sub-base tank is compromised through corrosion, impact damage, or seal failure, it can create both a fire hazard and an environmental liability, making prompt replacement with a correct OEM part essential.
