Key Features
- Genuine OEM Construction — Manufactured to the exact material and dimensional specifications of the original DEF tank body, ensuring proper fluid containment and structural integrity in demanding generator environments.
- Direct-Fit Replacement — Engineered to install in the original mounting position on the DCA70SSIU4F with all attachment points and port locations matching the factory assembly.
- Confirmed DCA70SSIU4F Fitment — Specifically built for the DCA70SSIU4F ultra-silent Isuzu Tier 4 generator; verify your model code before ordering to ensure a match.
- DEF System Integrity — A sound tank body prevents DEF fluid loss and contamination, keeping the selective catalytic reduction (SCR) system supplied and the generator in emissions compliance.
- Emissions System Compliance — Maintaining an intact DEF tank is critical to Tier 4 emissions compliance; a cracked or compromised body can trigger fault codes and take the machine offline.
The DEF (Diesel Exhaust Fluid) tank body serves as the structural housing that stores and protects the DEF fluid supply used by the generator's selective catalytic reduction system to reduce nitrogen oxide emissions. On Tier 4 machines like the DCA70SSIU4F, the SCR system depends on a continuous, uncontaminated DEF supply — a cracked or failed tank body can cause fluid leaks, sensor faults, and forced generator shutdowns. Replacing a damaged tank body with a genuine Multiquip assembly restores full DEF system function and keeps the unit running within its required emissions parameters.
