The Genie 1257781GT DEF Tank, 10L is a genuine OEM component designed for the Genie GTH-1056 telehandler. This part is specific to the aftertreatment system of each individual engine configuration — an engine serial number is required at the time of ordering to ensure the correct tank is supplied for your machine. As a genuine Genie OEM part, it is built to the same standards as the original component it replaces.
Key Features
- Genuine OEM Construction — Sourced directly from Genie, this DEF tank meets the same material and dimensional standards as the original, ensuring a correct, dependable fit in the aftertreatment system.
- Engine-Specific Fitment — Aftertreatment configuration varies by engine. An engine serial number is required when ordering to confirm the correct tank for your specific GTH-1056 unit.
- DEF System Integrity — A sound DEF tank maintains proper fluid storage and supply to the aftertreatment system, supporting emissions compliance and uninterrupted machine operation.
- Direct Application for GTH-1056 — Designed specifically for the Genie GTH-1056 telehandler, this part fits without adaptation when matched to the correct engine configuration.
- Emissions System Compliance — Using the correct OEM DEF tank helps ensure the aftertreatment system functions as designed, which is critical for meeting applicable emissions standards on the GTH-1056.
A DEF (Diesel Exhaust Fluid) tank stores the urea-based fluid used by the engine's aftertreatment system to reduce exhaust emissions. The tank feeds DEF to the SCR (Selective Catalytic Reduction) system at the rate the engine management system demands. A cracked, leaking, or incompatible tank can interrupt DEF supply, trigger fault codes, and cause the machine to derate or shut down. Because DEF aftertreatment configuration is specific to each engine, cross-reference part number 1257781GT against your GTH-1056 parts manual and have your engine serial number on hand before placing your order.
