Wacker Neuson 5100036418 Locking Fuel Cap Option

The Wacker Neuson 5100036418 Locking Fuel Cap Option is a genuine OEM component designed for the LTV6K, LTV6L, and LTV8K light tower series. As a direct OEM replacement, this locking fuel cap is sourced from Wacker Neuson and built to the exact specification of the original part — ensuring proper sealing, thread engagement, and tamper resistance on your machine. This option is confirmed to fit LTV6K, LTV6L, and LTV8K light towers, making it a straightforward, verified replacement for operators managing fuel security on active job sites. If your existing fuel cap is worn, cracked, or no longer locks, this part restores full functionality without guesswork.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and thread specification, delivering a consistent, fuel-tight seal that prevents leaks and fuel contamination.
• Locking Security — The integrated locking mechanism protects against unauthorized fuel access and deters theft — a practical necessity for unattended light tower deployment.
• Direct-Fit Replacement — Threaded to match the original fuel filler neck on LTV series light towers, this cap installs using the same mounting interface as the factory unit.
• Confirmed LTV Series Fitment — Verified for the LTV6K, LTV6L, and LTV8K light towers, so you can order with confidence knowing the part number has been matched to your machine family.
• Fuel System Protection — A properly sealing, lockable cap prevents fuel evaporation, contamination, and spillage — all of which can affect engine performance and extend service intervals on the light tower's power unit.

The fuel cap seals the fuel tank filler neck and prevents fuel from escaping during transport, operation, or while the machine sits idle. On a light tower like the LTV6K, LTV6L, or LTV8K, a compromised cap can allow dirt, debris, or moisture into the fuel system, leading to injector or carburetor issues and unplanned downtime. The locking feature adds a layer of security, preventing unauthorized access to the fuel supply — an important consideration when towers are deployed unattended at overnight or remote sites. A worn or broken cap that no longer seals or locks should be replaced promptly to maintain clean fuel delivery and site security.
