The Multiquip EE40550 is a genuine OEM Sub-Base Double Wall Tank UL142 12Hr 40.5 designed for UL142 series equipment. As a direct OEM replacement, this tank meets the same standards as the original unit it replaces, ensuring a correct, confidence-inspiring installation. Sourced directly through authorized channels, the part is the right choice when you need an exact-fit fuel containment solution for your Multiquip generator setup. Confirmed fitment for UL142 series models makes parts selection straightforward.
Key Features
- Double-Wall Containment Construction — Built with dual-wall design per UL 142 certification standards, providing secondary containment that prevents fuel leaks from reaching the ground or surrounding environment.
- UL 142 Listed — Carries the UL 142 listing required for above-ground flammable liquid storage, supporting compliance with fire code and site safety regulations where fuel containment standards are enforced.
- 12-Hour Fuel Capacity — Sized for extended run capability, allowing your generator to operate through a full 12-hour shift without refueling interruption.
- Genuine OEM Part — The Multiquip EE40550 is sourced as an authentic OEM component, matching the original tank's dimensions, fittings, and mounting interface for a direct drop-in installation.
- Fits UL142 Series Equipment — Confirmed fitment for Multiquip UL142 series generator configurations, eliminating guesswork when ordering a replacement sub-base fuel tank.
A sub-base fuel tank mounts directly beneath the generator set, serving as both the structural base for the unit and an integrated fuel supply reservoir. The double-wall construction adds a secondary containment layer around the inner fuel tank, capturing any leaks before they can escape to the surface below — a requirement on many commercial and government job sites. When a sub-base tank corrodes, develops weld failures, or loses its secondary containment integrity, it can result in fuel loss, site contamination, and failed inspections; replacing it with a certified OEM unit like the part restores both operational capacity and compliance standing.
