The Multiquip M5331401804 is a genuine OEM DEF Tank Hose designed for the DCA super-silent diesel generator series, including the DCA180SSJU4F, DCA220SSJU4F2, DCA150SSJU4F2, and DCA300SSJU4F2. As a factory-authorized replacement, this hose is built to the exact material and dimensional specifications required to maintain proper DEF fluid routing in Tier 4 emissions-compliant generator systems. Sourcing the correct OEM component matters here — an ill-fitting or incompatible hose can compromise your machine's DEF delivery circuit and trigger emissions faults. Part number M5331401804 is the direct replacement for these generator models and installs without modification.
Key Features
- OEM-Grade DEF Compatibility: — Constructed from materials rated to handle diesel exhaust fluid without degradation, cracking, or chemical breakdown over time.
- Direct-Fit Replacement: — Matches the original routing path, connection points, and hose diameter for a clean, secure installation into the existing DEF tank assembly.
- Confirmed Fitment: — Verified for DCA180SSJU4F, DCA220SSJU4F2, DCA150SSJU4F2, and DCA300SSJU4F2 super-silent diesel generator models.
- Protects Tier 4 Emissions Systems: — A properly functioning DEF hose keeps the selective catalytic reduction (SCR) system operating within spec, helping your generator stay compliant and avoid emissions-related shutdowns.
- Genuine Multiquip OEM Part: — Sourced directly from Multiquip, ensuring the part meets the same build standards as the original component installed at the factory.
The DEF tank hose routes diesel exhaust fluid from the storage tank to the dosing system that feeds the selective catalytic reduction (SCR) circuit — a key part of Tier 4 final emissions compliance on these generators. Without a properly sealed and chemically resistant hose, DEF fluid can leak, crystallize at connection points, or fail to reach the injector at the correct flow rate, causing the SCR system to fault and potentially forcing the generator into a derated or shutdown condition. Replacing a worn, cracked, or leaking DEF hose promptly keeps the emissions system functioning correctly and protects the generator from unnecessary downtime tied to avoidable fault codes.
