The Multiquip EE58498 DEF Heated Hose Suction Return Lines is a genuine OEM assembly designed for the SG1400C4F and SG1600C4F Tier 4 diesel-powered studio generators. This factory-sourced component ensures the diesel exhaust fluid (DEF) circuit operates at the correct temperature range to prevent crystallization and maintain uninterrupted fluid flow through the suction and return line circuit. Sourced directly through Multiquip's OEM supply chain, EE58498 meets the exact design specifications of the original installation. If you are servicing either the SG1400C4F or SG1600C4F, this is the correct replacement hose assembly for those models.
Key Features
- Integrated Heating Element: — Built-in heating circuitry maintains DEF fluid temperature above freezing, preventing urea crystallization that would block the suction and return lines and trigger fault codes.
- Genuine OEM Construction: — Manufactured to the same material and dimensional specifications as the original hose assembly, ensuring correct connector fit and fluid-rated inner liner integrity throughout the DEF circuit.
- Direct-Fit Replacement: — Engineered as a drop-in replacement for the SG1400C4F and SG1600C4F studio generators, connecting directly to the existing DEF tank and dosing module ports without modification.
- Protects Tier 4 Emissions Compliance: — A functioning DEF hose assembly is critical to the SCR aftertreatment system operation; a failed or leaking hose can cause the generator to derate or shut down to remain within EPA Tier 4 emissions requirements.
- Covers Both Suction and Return Lines: — This assembly addresses the complete DEF fluid loop, replacing both the suction and return line segments in a single service event to restore full system integrity.
The DEF heated hose assembly carries diesel exhaust fluid from the storage tank to the dosing injector and returns unused fluid back to the tank as part of the selective catalytic reduction (SCR) emissions system. The integrated heating element keeps the urea-based fluid from freezing in cold operating conditions — frozen or restricted DEF lines will starve the SCR system of fluid, causing the generator to derate or fault out entirely. Replacing a degraded or damaged hose with a genuine OEM assembly like the Multiquip EE58498 restores proper fluid delivery and keeps the emissions system functioning as designed.
