The Multiquip EE58497 DEF Heated Hose Pressure Line is a genuine OEM component designed for SG1400C4F and SG1600C4F diesel-powered studio generators. As an authorized Multiquip OEM part, the part is manufactured to the exact specifications required for proper DEF delivery in Tier 4 emissions systems. This part installs as a direct replacement, ensuring the pressurized DEF line integrates seamlessly with the existing SCR aftertreatment plumbing on compatible generator models. DHS Equipment stocks this part to keep your generator performing at full compliance and operational capacity.
Key Features
- Genuine OEM DEF Compatibility — Built to the precise pressure and chemical-resistance ratings required for diesel exhaust fluid delivery in Tier 4 SCR systems, preventing fluid degradation or line failure.
- Integrated Heating Element — The built-in heating circuit keeps DEF fluid from freezing in cold operating conditions, maintaining uninterrupted flow through the pressure line.
- Direct-Fit Replacement — Engineered to match the original routing, connector ends, and line diameter of the EE58497 as fitted at the factory, so installation requires no splicing or adapters.
- Confirmed Fitment — Verified for SG1400C4F and SG1600C4F Multiquip studio generators; always cross-reference your model code before ordering.
- Emissions System Integrity — A failed or leaking DEF pressure line can trigger fault codes, force the generator into derate mode, or cause non-compliance with Tier 4 emissions regulations — this OEM replacement restores correct system function.
The DEF Heated Hose Pressure Line carries diesel exhaust fluid from the DEF tank to the dosing injector within the selective catalytic reduction (SCR) system. The heating element embedded in the hose prevents DEF — which freezes at approximately 12°F (–11°C) — from solidifying and blocking the line during cold-weather operation. When this hose develops a leak, loses heating function, or becomes damaged, the SCR system can no longer accurately dose the exhaust stream, resulting in elevated NOx emissions, diagnostic fault codes, and potential power derate on Tier 4-compliant generators.
