Multiquip RE560902 DEF Suction Line - OEM Replacement Part

The DEF suction line transfers diesel exhaust fluid from the tank to the dosing system on Multiquip Super Silent generators equipped with Tier 4 Final emissions technology. This critical fuel system component ensures proper DEF flow to maintain SCR catalyst operation and prevent engine shutdowns due to emissions system faults.

This genuine OEM line is essential for generators that experienced the mandatory DEF tank cover plate update bulletin dated August 23, 2017. Units affected by that service bulletin can experience engine shutdowns when DEF temperatures reach or exceed 150°F (65°C), making proper DEF system component function critical for reliable operation. The suction line works in conjunction with the DEF tank assembly to maintain fluid at proper operating temperature and flow rate.

Compatible with the following Multiquip Super Silent generator models:

• DCA150SSJU4F
• DCA220SSJU4F
• DCA300SSJU4F
• DCA300SSJU4F2
