Multiquip RE560897 DEF Pressure Line - OEM Replacement Part for Super Silent Generators

The DEF pressure line delivers Diesel Exhaust Fluid under pressure from the tank to the dosing system in Multiquip Super Silent generators equipped with emissions control systems. This critical emissions component ensures proper DEF flow to meet EPA Tier 4 Final requirements and prevent engine shutdown from ECM fault codes. Failure of the DEF pressure line can result in loss of DEF delivery, triggering fault codes and potential engine shutdown to protect the emissions system.

These Super Silent generators use DEF systems that require proper fluid temperatures and pressure to function correctly. The Engine Control Module monitors DEF system performance continuously, and any pressure loss or delivery failure will generate fault codes. Regular inspection of the DEF pressure line during maintenance intervals helps prevent unexpected downtime, especially in units operating under extended light load conditions or extreme ambient temperatures where DEF system stress is increased.
