Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring the tank walls, fittings, and capacity rating match the factory unit exactly.
- 300-Gallon DEF Capacity — Full-volume replacement tank maintains the complete fluid storage capacity of the DEFTANK302 system without compromise.
- Direct-Fit for DEFTANK302 — Engineered as a drop-in replacement for MQ Power Fuel and DEF Tank systems; mounting points and connections align with the original installation.
- DEF-Compatible Materials — Built from materials rated for Diesel Exhaust Fluid storage, resisting the corrosive and crystallizing properties of DEF to preserve tank integrity over time.
- Protects Emissions System Performance — A properly functioning DEF tank ensures uninterrupted fluid supply to the emissions system, preventing SCR system faults and keeping equipment compliant with Tier 4 emissions requirements.
The DEF 300 Gallon Tank stores Diesel Exhaust Fluid for use in equipment equipped with a Selective Catalytic Reduction emissions system. DEF is injected into the exhaust stream to break down harmful nitrogen oxide emissions into harmless nitrogen and water vapor. When the tank cracks, leaks, or degrades, the DEF supply is interrupted, which can trigger fault codes, force the machine into a derate condition, and ultimately prevent operation — making timely replacement critical to keeping emissions-controlled equipment running and compliant.
