Cross-reference part number 1258475GT against your machine's parts manual before ordering to confirm it is the correct item for your serial number and configuration.
Key Features
- Genuine OEM Construction — Built to Genie's exact material and pressure specifications for DEF service, ensuring the hose handles the thermal and chemical demands of DEF return routing.
- Integrated Heating Element — The built-in heating element prevents DEF from freezing in cold-weather operation, keeping the DEF circuit flowing when temperatures drop on the jobsite.
- Exact-Fit Replacement — Engineered as a direct replacement for the original hose, matching OEM routing, connector ends, and length so it installs without modification.
- Confirmed Fitment — Designed for Genie GTH-844, GTH-1056, and GTH-1256 telehandlers; verify against your parts manual to match the correct configuration.
- Emissions System Integrity — A sound DEF return hose maintains proper DEF flow through the SCR system. A cracked, leaking, or non-heating hose can disrupt DEF delivery, trigger fault codes, and force the machine into a derate condition.
A heated DEF return hose carries diesel exhaust fluid back through the DEF circuit while an internal heating element keeps the fluid from solidifying in freezing temperatures. On machines equipped with a selective catalytic reduction system, uninterrupted DEF flow is essential — if the return hose cracks, leaks, or loses its heating function, DEF delivery becomes unreliable, which can trigger warning codes and put the machine into a power-derate mode. Replacing a failed hose with the correct OEM part restores proper DEF circulation and keeps the emissions system operating as designed.
