The Multiquip RE560894 is a genuine OEM DEF Pressure Line designed for Multiquip super-silent and diesel-powered generator models including the DCA70SSJU4F, DCA150SSJU4F, and DCA220SSJU4F series. As a direct OEM replacement, this line is manufactured to the same specifications as the original component and installs without adaptation. Keeping the DEF delivery path intact is critical to Tier 4 emissions compliance, making RE560894 the correct choice when the original line shows wear, cracking, or fluid loss. DHS Equipment stocks genuine Multiquip parts to help you get your generator back in service with confidence.
Key Features
- Genuine OEM Construction — Built to the same material and pressure tolerances as the original DEF line, ensuring the fluid integrity the Tier 4 emissions system depends on.
- Direct-Fit Replacement — Matches the original routing, end fittings, and line diameter for a straightforward swap on compatible DCA series generators.
- Compatible with DCA Series Generators — Confirmed fitment for DCA70SSJU4F, DCA150SSJU4F, and DCA220SSJU4F super-silent and diesel-powered units.
- Emissions System Integrity — A compromised DEF pressure line can interrupt DEF flow to the SCR system, triggering fault codes, derate conditions, or a full generator shutdown — this OEM line restores correct fluid delivery.
- Regulatory Compliance — Proper DEF system function is required for Tier 4 Final emissions compliance; using an OEM-spec pressure line supports continued adherence to EPA standards on regulated job sites.
The DEF Pressure Line carries diesel exhaust fluid from the DEF tank to the dosing module, where it is injected into the exhaust stream to reduce nitrogen oxide emissions in Tier 4 Final engines. Maintaining consistent pressure throughout this line is essential — if the line cracks, degrades, or develops a leak, DEF flow is interrupted, which can trigger warning codes, engine derate, or automatic shutdown to protect emissions compliance. Replacing a worn or damaged line with a genuine OEM part like the RE560894 restores the system to its designed operating state and prevents unplanned outages.
