Multiquip 8981562981 DEF Tank Cover Assembly - OEM Replacement Part

The DEF (Diesel Exhaust Fluid) tank cover assembly protects the DEF tank fill point and venting system on Tier 4 Final compliant super silent generators, preventing contamination of the emission control fluid that's critical for SCR (Selective Catalytic Reduction) system operation. This OEM cover assembly maintains proper sealing to keep dirt, debris, and moisture out of the DEF tank while allowing proper pressure equalization during fill and draw cycles.

Designed specifically for Multiquip's super silent generator series, this cover assembly ensures your DEF system remains sealed and contaminant-free. DEF contamination is a leading cause of SCR system failure and can trigger fault codes, reduced engine performance, or complete shutdown. Regular inspection of the tank cover for cracks, damaged seals, or loose fittings should be part of your routine maintenance schedule, especially in harsh operating environments or high-duty cycle applications.

Compatible with the following Multiquip generator models:
