The Multiquip EE54904 Subbase Tank DW UL142 24HR is a genuine OEM fuel containment subbase designed for UL142-rated standby generator applications including the MQP50/60IV series. This component is sourced directly from Multiquip and meets the UL142 standard for aboveground flammable liquid storage, making it the correct replacement when the original tank requires service or swap-out. Confirmed fitment for UL142-designated equipment ensures a direct, no-guesswork installation. DHS Equipment supplies this as an authorized Multiquip OEM part, giving you confidence in both sourcing and specification.
Key Features
- UL142 Certified Construction — Built to UL142 standards for aboveground steel fuel tanks, confirming the tank meets established safety and containment requirements for standby generator installations.
- 24-Hour Fuel Capacity Rating — Sized and rated for 24-hour runtime fuel supply, supporting extended generator operation without the need for manual refueling during critical power events.
- Direct OEM Replacement — Manufactured to the original Multiquip specification for UL142-rated subbase configurations, so it integrates with the existing generator base frame and fuel system connections.
- Genuine Multiquip OEM Part — Authentic Multiquip component carrying part number EE54904, not a generic substitute, ensuring material grade and dimensional accuracy match the original equipment design.
- Double-Wall (DW) Containment Design — The double-wall construction provides secondary containment, helping to meet environmental compliance requirements common on commercial and industrial generator installations.
A subbase fuel tank is an integrated fuel storage unit mounted directly beneath the generator set, serving as both the structural base and the onsite fuel supply for the engine. The double-wall design adds an outer containment layer around the primary fuel tank, capturing any leaks before they reach the ground — a requirement on many regulated or sensitive sites. When a subbase tank corrodes, develops a breach, or fails inspection, the generator loses its compliant fuel storage, which can halt operation or create a regulatory issue; replacing it with a certified OEM unit like the part restores both function and compliance.
