The Multiquip EE30781 is a genuine OEM Sub-Base Double Wall Tank UL142 12Hr 150 G designed for UL142 series generator equipment. As a factory-original component, it is manufactured to meet the exact specifications required for safe and compliant fuel storage in Multiquip generator applications. This tank is confirmed to fit UL142 series units, making it a direct drop-in replacement for worn or damaged sub-base fuel tank assemblies. Sourced directly through authorized Multiquip supply channels, the part ensures your equipment returns to full operational status with confidence.

Key Features

• UL142-Listed Double Wall Construction — Secondary containment wall meets UL142 standards for aboveground flammable liquid storage, providing a critical layer of protection against fuel leaks.
• 12-Hour Fuel Capacity at 150 Gallons — Sized to support extended generator runtime without refueling interruptions, keeping operations continuous through demanding shifts.
• Genuine OEM Component — Manufactured to Multiquip's original design tolerances, ensuring correct port placement, mounting dimensions, and material grade match the original tank exactly.
• Direct Replacement for UL142 Series Generators — Engineered specifically for UL142 series equipment, allowing straightforward installation without modification to fuel lines or mounting hardware.
• Fuel System Integrity — A sound, correctly sealed sub-base tank prevents fuel contamination, pressure loss, and hazardous spills that can compromise generator performance and site safety.
• Regulatory Compliance Ready — Double wall design supports compliance with EPA and NFPA 30 secondary containment requirements commonly enforced on commercial and industrial job sites.

A sub-base double wall fuel tank sits beneath the generator set and serves as the primary fuel reservoir, feeding the engine while containing any potential leaks within its outer wall. The double wall design acts as a built-in secondary containment system, capturing any fuel that escapes the inner tank before it can reach the ground or surrounding environment. When a sub-base tank develops cracks, corrosion, or compromised seals, the risk of fuel loss, engine starvation, and regulatory non-compliance increases significantly — making timely replacement with a genuine OEM part essential.
