Sourced directly from Genie, this plate is manufactured to the same specifications as the original part installed at the factory, ensuring a correct, trouble-free installation. Cross-reference part number 1258705GT against your GTH-1056 parts manual to confirm it is the right component for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured by Genie to original dimensional and material specifications, ensuring the plate seats and seals exactly as intended on the DEF tank fill point.
- Correct 10L Tank Sizing — Sized specifically for the 10L DEF tank configuration, so this plate aligns and secures without modification or adaptation to adjacent hardware.
- Direct-Fit for GTH-1056 — Verified fitment for the Genie GTH-1056 telehandler; matches the original mounting pattern and hardware interface of the fill assembly.
- DEF System Integrity — A properly fitted fill plate keeps the DEF tank sealed against contamination and spillage, protecting the emissions system and keeping the machine compliant with applicable standards.
- Long-Term Durability — Built from materials rated for repeated exposure to DEF fluid, which is corrosive to many metals, reducing the risk of premature degradation at the fill point.
The DEF tank fill plate covers and seals the fill opening on the diesel exhaust fluid tank, protecting the fluid inside from dirt, moisture, and other contaminants that can degrade DEF quality and trigger emissions faults. On machines equipped with selective catalytic reduction systems, maintaining clean, uncontaminated DEF is essential — a damaged or missing fill plate exposes the tank to contamination that can affect system performance and trigger fault codes. Replacing a cracked, corroded, or damaged plate promptly keeps the fill point secure and the DEF system functioning as designed.
