Multiquip EE45312 Sub-Base Double Wall Tank UL142 1600 Gals

The Multiquip EE45312 Sub-Base Double Wall Tank UL142 1600 Gals is a genuine OEM fuel containment tank designed for UL142 series generator and equipment configurations. As a direct OEM replacement, this tank is built to meet the same standards as the original unit it replaces, ensuring correct dimensional fit and full compatibility with UL142-rated installations. DHS Equipment supplies this part direct from Multiquip, so you can order with confidence knowing you are receiving an authentic component backed by the manufacturer.

Key Features

• UL142 Listed Double-Wall Construction — Built to meet UL142 secondary containment requirements, providing a compliant outer containment layer around the primary fuel tank to prevent leaks and spills from reaching the surrounding environment.
• 1,600-Gallon Capacity — Large-volume sub-base design supports extended run times for generators and stationary equipment without frequent refueling intervals.
• Direct OEM Replacement — Sourced directly from Multiquip as a genuine OEM component, this tank mounts as a sub-base unit and integrates with UL142 series equipment without secondary modification to the mounting interface.
• Fuel System Integrity — A correctly installed double-wall sub-base tank maintains a sealed fuel supply, preventing contamination and protecting engine performance over extended operation cycles.
• Regulatory Compliance — The UL142 listing is a key requirement for above-ground flammable liquid storage at many commercial, industrial, and government job sites — using a certified replacement tank helps maintain site compliance with applicable fuel storage codes.

A sub-base double-wall tank serves as both the structural foundation and the primary fuel storage vessel for stationary generator and power equipment installations. The double-wall design adds a secondary containment layer around the inner fuel tank, capturing any leaks before they can reach the ground or surrounding structure — a critical safety and regulatory feature for above-ground fuel storage. When the primary wall is compromised or the tank no longer meets UL142 containment standards, replacing it with a certified OEM unit like the part restores both structural support and compliant fuel containment to the installation.
