Multiquip EE47990 Fuel Tank Sub Base Double Wall UL 142 550

The Multiquip EE47990 is a genuine OEM Fuel Tank Sub Base Double Wall UL 142 550 designed for UL142 series equipment. As a direct OEM component sourced from Multiquip, it is manufactured to the same specifications as the original part, ensuring a correct, confidence-inspiring installation. This tank assembly is built to meet UL 142 standards, making it the right choice when compliance and containment integrity matter. Confirm your model code is UL142 before ordering to ensure proper fitment.

Key Features

• UL 142 Compliant Construction — Built to Underwriters Laboratories Standard 142 for aboveground steel fuel storage tanks, ensuring the tank meets recognized safety and containment requirements.
• Double Wall Design — The secondary containment wall provides an added layer of spill and leak protection, a critical feature for stationary fuel storage applications.
• Genuine OEM Component — Sourced directly from Multiquip, this part matches the original tank assembly in material, dimensions, and structural integrity — no guesswork on fitment.
• Sub Base Integration — Designed as a sub base mounted unit, it installs directly beneath compatible Multiquip generator sets, maintaining the correct structural footprint and fuel feed geometry.
• 550-Gallon Capacity Rating — Sized at 550 gallons to support extended run times for compatible standby or studio generator applications, reducing the frequency of manual refueling.
• Fits UL142 Series Equipment — Confirmed fitment for Multiquip UL142 designated equipment — verify your model code before ordering.

A sub base fuel tank sits directly beneath a generator set and serves as both the structural base and the primary fuel supply for the unit. The double wall construction adds a secondary containment layer around the inner fuel tank, capturing any leaks or seepage before they can reach the ground — a requirement in many jurisdictions for stationary fuel storage. When the tank is compromised, corroded, or no longer meets code compliance, replacing it with a genuine OEM unit like the part ensures the generator system continues to operate safely and within applicable regulatory standards.
