DHS Equipment supplies this part direct, so you can order with confidence that you are receiving the authentic Genie component.
Key Features
- Genuine OEM Construction — Built to Genie's original material and dimensional specifications, with a heated design that maintains DEF flow in cold operating conditions.
- Integrated Heating Element — The built-in heating function prevents DEF crystallization inside the suction line, keeping the DEF system operating correctly across a wide temperature range.
- Direct OEM Replacement — Designed to connect and route exactly as the original, with no adaptation needed to fit the GTH-844, GTH-1056, or GTH-1256.
- Confirmed Telehandler Fitment — Fits Genie GTH series telehandlers; cross-reference part number 1258474GT against your machine's parts manual to confirm applicability to your unit.
- Emissions System Integrity — A sound DEF suction hose is essential for correct DEF delivery. A cracked, blocked, or unheated line can interrupt DEF flow, triggering fault codes and deration of the machine.
A heated DEF suction hose draws diesel exhaust fluid from the tank and delivers it to the DEF pump, while an internal heating element keeps the fluid from freezing in cold weather — DEF crystallizes at around 12°F (-11°C), which can block an unheated line entirely. When this hose cracks, leaks, or loses heating function, DEF supply to the dosing system is interrupted, which typically triggers warning codes and causes the engine to derate or limit output until the fault is cleared. Replacing a failed hose with the correct OEM part restores proper DEF flow and keeps the machine's emissions system operating as designed.
