Key Features
- UL142 Certified Double-Wall Construction — Built to meet UL142 secondary containment standards, ensuring the tank satisfies code requirements for above-ground fuel storage at the point of installation.
- 12-Hour Fuel Capacity — Sized to support 12 hours of continuous generator runtime, reducing the frequency of refueling interruptions during extended operations.
- Direct Sub-Base Integration — Designed to mount directly under the generator set as a structural base, eliminating the need for external fuel supply infrastructure and keeping the footprint compact.
- Genuine OEM Part — Sourced directly from Multiquip, EE43661 matches the original tank specification in materials, wall thickness, and fittings — no adaptation or guesswork on fitment.
- Fits UL142 Series Generator Configurations — Confirmed fitment for UL142 series Multiquip generator applications; verify your model code prior to ordering.
- Fuel System Safety Compliance — The double-wall design provides a secondary containment barrier, helping operators meet environmental and fire code regulations governing generator fuel systems.
A sub-base fuel tank sits beneath the generator set and serves as both the structural mounting base and the onsite fuel reservoir. The double-wall design consists of an inner tank that holds the fuel and an outer wall that acts as secondary containment — capturing any leaks or seepage before they can reach the surrounding environment. This construction is commonly required by fire codes, environmental regulations, and insurance policies for standby and stationary generator installations. A damaged, corroded, or non-compliant tank can result in fuel leaks, failed inspections, or unplanned downtime during a critical power event, making correct replacement with a certified OEM part essential.
