The Wacker Neuson Fuel Tank Cap is a genuine OEM component designed for the LT, LTP, and LTW series light towers. As a direct factory replacement, this cap ensures a proper seal on the fuel tank of your Wacker Neuson light tower, maintaining fuel system integrity during operation and transport. Compatible across a wide range of LT4K, LTP4K, LT4Z, LTP4Z, LTW4Z, LTW4K, LTW6Z, LT4SK, LTP4SK, LT4SZ, and LTP4SZ models, this is the correct OEM part to have on hand for routine maintenance or emergency field replacement.
Key Features
- Genuine OEM Seal Integrity — Manufactured to Wacker Neuson's exact fit and material specifications, ensuring the cap threads and seals correctly against the tank neck with no leaks.
- Drop-In Replacement — Threads directly onto the original fuel tank fill neck with no modification to the tank or cap mount needed.
- Broad LT/LTP/LTW Series Fitment — Confirmed for LT4K, LTP4K, LT4Z, LTP4Z, LTW4Z, LTW4K, LTW6Z, LT4SK, LTP4SK, LT4SZ, and LTP4SZ light tower models.
- Fuel Containment on the Move — A correctly sealing fuel tank cap prevents spillage and fuel vapor loss when towing or repositioning the light tower between job locations.
- Fire and Spill Safety — A cracked, missing, or improperly sealed fuel cap on a diesel light tower creates a fuel spillage and ignition risk; replacing it promptly keeps the unit operating safely.
The fuel tank cap seals the fill opening on the light tower's diesel fuel tank, preventing fuel from spilling during transport and keeping contaminants such as dust, debris, and moisture out of the fuel supply. A secure seal also reduces fuel vapor emissions from the tank. When the cap is cracked, cross-threaded, or missing its seal, the fuel system is exposed to contamination that can clog filters and injectors, and fuel spillage becomes a real hazard on-site. Replacing a worn or damaged cap with the correct OEM part restores the fuel system's first line of protection.
