Multiquip EE54646 Fuel Tank Sub-Base 300 Gallon Double Wall UL142

The Multiquip EE54646 is a genuine OEM Fuel Tank Sub-Base 300 Gallon Double Wall UL142 designed for UL142 series equipment. This tank is manufactured to meet Multiquip's original specifications, ensuring a direct-fit replacement that integrates correctly with the base frame and fuel system of compatible units. Sourced directly through authorized channels, EE54646 delivers the construction-grade durability and containment performance required for extended stationary fuel storage applications.

Key Features

• Double-Wall Containment Construction — The double-wall design provides an integral secondary containment layer, helping to contain fuel in the event of an inner tank breach and supporting environmental compliance on regulated jobsites.
• UL 142 Listed Tank — Built and listed to UL 142 standards for steel above-ground flammable liquid storage tanks, confirming the tank meets recognized safety and construction benchmarks for above-ground fuel storage.
• 300-Gallon Capacity — Sized at 300 gallons to support extended run times for generator sets and other stationary power equipment without frequent refueling interruptions.
• Genuine OEM Replacement — As an authentic Multiquip part, this part matches the original tank's dimensions, mounting footprint, and connection points, allowing straightforward installation on UL142 series sub-base configurations.
• Sub-Base Integration — Engineered as a sub-base tank, it mounts directly beneath the generator or power unit frame, keeping the overall footprint compact while centralizing fuel supply at the base of the equipment.

A sub-base fuel tank is an integrated fuel storage unit mounted directly beneath a generator set or stationary power unit, forming part of the machine's base structure while simultaneously serving as the primary fuel reservoir. The double-wall construction means a second steel wall surrounds the inner tank, creating a monitored interstitial space that catches any leakage before it reaches the environment — a requirement in many local codes and EPA spill-prevention plans. When a sub-base tank develops a leak, corrodes through, or fails a containment inspection, replacing it with the correct OEM unit like the Multiquip EE54646 ensures the fuel system, venting, and level sensing components reconnect without modification.
