The Multiquip EE51481 Sub-Base Double Wall 12hr 400 Gal Tank is a genuine OEM component designed for R-400G equipment. As an authentic Multiquip part, EE51481 is manufactured to the exact specifications required for proper fit and function within the R-400G fuel storage system. This sub-base tank is engineered to integrate directly with the unit's base structure, providing a self-contained, code-compliant fuel supply capable of supporting extended runtime operation.
Key Features
- Genuine OEM Construction — Double-wall tank integrity is validated to Multiquip's exact material and dimensional specifications, ensuring structural soundness and leak containment performance expected from an OEM fuel storage component.
- Double-Wall Secondary Containment — The inner and outer wall design provides a built-in secondary containment barrier, meeting standard environmental and safety requirements for stationary fuel storage on generator base tanks.
- 12-Hour Runtime Capacity — The 400-gallon capacity is sized to deliver approximately 12 hours of continuous operation, supporting extended run cycles without manual refueling interruptions.
- Direct Fitment for R-400G — Engineered as an OEM replacement specifically for the R-400G, this tank drops into the sub-base frame without modification to mounting points or fuel line connections.
- Fuel System Integrity — A properly sealed and structurally sound sub-base tank prevents fuel leaks and pressure loss that can lead to generator shutdowns, operational failures, or environmental compliance issues on the worksite.
- Environmental and Operational Compliance — Double-wall sub-base tanks are commonly required by local regulations for stationary fuel storage; replacing a compromised tank restores the unit to a compliant configuration.
The sub-base double wall tank serves as the primary fuel reservoir integrated into the base structure of stationary generator equipment. The double-wall design means a secondary outer shell surrounds the inner fuel tank, capturing any leaks before they reach the ground — a critical requirement for environmentally sensitive or regulated job locations. When this tank is cracked, corroded, or compromised in any way, it can cause fuel loss, failed runtime targets, and potential regulatory violations; replacing it with the correct OEM unit restores full capacity and containment integrity.
