Multiquip M3331402604 DEF Tank Hose - OEM Replacement Part

This DEF (Diesel Exhaust Fluid) tank hose is a critical component in Multiquip Super Silent generator emission systems, connecting the DEF tank to the selective catalytic reduction (SCR) system. This hose was specifically addressed in Multiquip's mandatory service bulletin GSP20170818 dated August 23, 2017, which identified DEF system issues that could cause engine shutdowns when DEF temperatures reach or exceed 150°F (65°C). Replacing failed or deteriorated DEF tank hoses as part of the mandatory update procedure ensures proper fluid flow and prevents overheating conditions that lead to unexpected generator shutdowns in the field.

Designed for demanding industrial and rental applications, this genuine OEM hose maintains the integrity of the DEF delivery system under high-temperature operating conditions. Regular inspection of DEF system components, including hoses and connections, is essential preventive maintenance for Tier 4 Final compliant generators.

Compatible with the following Multiquip Super Silent generator models:

• DCA150SSJU4F2
• DCA180SSJU4F
• DCA220SSJU4F2
• DCA300SSJU4F2
