- 24-Hour Fuel Capacity Rating — Sized to support extended run requirements, allowing generator systems to operate through prolonged duty cycles without refueling interruptions.
- Direct-Fit OEM Replacement — Engineered to the original design specifications for UL142 series equipment, matching mounting points, connections, and dimensional tolerances of the factory unit.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, the EE50551 carries full OEM traceability, ensuring the part you install matches the original tank in material grade and construction.
A sub-base double wall fuel tank sits beneath the generator set and serves as the primary fuel supply and containment system for the unit. The double-wall design creates a secondary barrier around the inner fuel tank, capturing any leaks or seepage before they reach the surrounding environment — a requirement in many jurisdictions for stationary generator installations. When a sub-base tank is compromised through corrosion, physical damage, or seal failure, it can pose both a regulatory compliance risk and a fuel delivery problem that prevents the generator from sustaining runtime. Replacing it with a correctly rated OEM unit restores both the containment integrity and the operational fuel reserve the system was designed around.
