Multiquip M3494114004 DEF Tank Cover Assembly (2 Pieces) - OEM Replacement Part

This DEF (Diesel Exhaust Fluid) tank cover assembly is a critical component for maintaining proper emissions system operation on Multiquip super silent generator models. The assembly consists of two pieces and includes an integrated rubber flap designed to block and divert incoming hot air from reaching the DEF fluid inside the tank. This design prevents heat-related degradation of the DEF fluid, which can cause crystallization, reduced effectiveness, and potential emissions system failures.

This cover plate assembly was introduced as part of a mandatory warranty campaign (GSP20170818) to address DEF fluid protection issues in affected generator models. The rubber flap creates an air barrier that maintains optimal DEF fluid temperature and prevents contamination, ensuring reliable operation of the emissions control system and preventing costly downtime due to DEF-related faults.
