Multiquip EE43772 Fuel Tank Sub Base Double Wall UL 142 UCTS

The Multiquip EE43772 Fuel Tank Sub Base Double Wall UL 142 UCTS is a genuine OEM component designed for UL142 series equipment. This sub base fuel tank is manufactured to meet the UL 142 standard for aboveground flammable liquid storage, making it a direct-fit replacement for Multiquip generator and power equipment installations that require a compliant integrated fuel supply. Sourced directly through Multiquip's authorized parts network, EE43772 ensures correct fit and regulatory compliance from day one.

Key Features

• UL 142 Compliant Construction — Double-wall design meets the Underwriters Laboratories standard for aboveground steel tanks storing flammable liquids, satisfying code requirements for fuel containment at the sub base level.
• Genuine OEM Part — Produced to Multiquip's exact engineering specifications, ensuring the tank dimensions, fittings, and structural ratings match the original unit on UL142 series equipment.
• Double-Wall Containment — The inner and outer wall construction provides a secondary containment barrier, protecting against fuel leaks and reducing environmental liability on the jobsite.
• Direct Sub Base Replacement — Engineered as an integrated base-mounted fuel reservoir, this tank mounts beneath the generator set as a structural and fuel-supply foundation in a single assembly.
• Fuel System Integrity — A properly sealed, code-compliant sub base tank maintains consistent fuel delivery to the engine and prevents contamination that can cause hard starts, rough running, or generator shutdowns.
• Regulatory Confidence for Permanent Installations — UL 142 certification is commonly required by fire marshals and AHJs (Authorities Having Jurisdiction) for standby and prime power generator installations — this tank helps meet those requirements.

A sub base fuel tank is an integrated fuel storage unit built into the base frame of a generator or power unit, combining structural support and on-board fuel supply in one assembly. The double-wall design means a secondary outer wall surrounds the primary fuel tank, creating an interstitial space that catches any leakage from the inner wall before it can reach the environment — a critical requirement for permanent and semi-permanent generator installations. When a sub base tank develops leaks, corrosion, or structural damage, it can compromise both fuel delivery to the engine and on-site safety compliance, making timely replacement with a correct OEM unit essential.
