The Multiquip EE60423 is a genuine OEM Outer DEF Fill Hose designed for DEFTANK1, DEFTANK2, and DEFTANK302 MQ Power Fuel and DEF Tank units. As a direct OEM replacement, this hose is manufactured to the exact 2-inch inner diameter and 8.5-inch length specification required for proper DEF routing in these tank systems. Sourced directly from Multiquip, the part ensures a correct, leak-free connection within the DEF fill path. Keeping the right part on hand helps maintain the integrity of your DEF system and avoids costly fluid contamination or spills.
Key Features
- OEM-Grade DEF-Compatible Material — Constructed to resist degradation from diesel exhaust fluid, which is highly corrosive to non-rated hose materials.
- Exact Dimensional Fit — Sized at 2-inch inner diameter and 8.5 inches in length to match the original routing and connection points in the fill line assembly.
- Confirmed Fitment for DEFTANK Series — Verified for use with DEFTANK1, DEFTANK2, and DEFTANK302 MQ Power Fuel and DEF Tank models.
- Leak-Free DEF Delivery — A correctly seated outer fill hose maintains a sealed flow path, preventing DEF spillage that can damage surrounding components and cause emissions system faults.
- Emissions System Integrity — DEF system components must meet strict material and dimensional tolerances to maintain proper SCR function; using the correct OEM hose supports compliance with emissions equipment requirements.
The outer DEF fill hose routes diesel exhaust fluid from the fill point into the DEF storage tank, forming a sealed pathway that keeps fluid clean and contained during the fill process. Because DEF is a urea-based solution that aggressively degrades standard rubber and non-rated plastics, the hose must be manufactured from compatible materials to prevent swelling, cracking, or contamination of the fluid. A worn or compromised fill hose can allow DEF to leak onto surrounding components or introduce contaminants into the tank, which can foul the selective catalytic reduction system and trigger emissions faults that take the machine out of service.
