The Wacker Neuson Fuel Pre-Filter is a genuine OEM component designed for the LTS4K, LTS4Y, LTS7K, LTS8K, LTS8L, and LTE4K series light towers. As a direct OEM part, it meets the exact same specifications as the original unit installed at the factory, so you can install it with confidence and get your equipment back on the job fast. Fitment spans both 50 Hz and 60 Hz configurations as well as trailer and skid-mounted variants across the LTS and LTE series. If you are cross-referencing by part number, is the correct replacement for all compatible configurations listed below.
Key Features
- OEM Filtration Specification — Engineered to the same micron rating and flow capacity as the original Wacker Neuson filter, ensuring consistent fuel delivery to the engine under load.
- Drop-In Replacement — Matches the original inlet and outlet dimensions and connection type, so it installs directly into the existing fuel line without adapters or modifications.
- Broad Series Compatibility — Confirmed fitment across LTS4K, LTS4Y, LTS7K, LTS8K, LTS8L, and LTE4K light towers in both 50 Hz and 60 Hz variants, covering trailer and skid-mounted configurations.
- Protects Engine Fuel System — Catches particulates and contaminants before they reach the fuel pump and injectors, helping prevent costly downstream component wear.
- Fuel System Safety — A correctly seated OEM pre-filter maintains a closed, leak-free fuel circuit, reducing the risk of fuel vapor exposure and fire hazard on the worksite.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100041144 carries full OEM traceability for fleet maintenance records and service documentation.
A fuel pre-filter sits in the fuel supply line upstream of the engine's fuel pump and primary filter. Its job is to catch dirt, rust, and debris from the fuel tank before they can reach and damage finer downstream components. When a pre-filter becomes clogged or bypassed, fuel flow to the engine is restricted, which can cause hard starting, rough running, or complete engine shutdown — leaving your light tower unable to operate during a critical shift. Replacing the pre-filter at regular service intervals is one of the lowest-cost ways to protect the entire fuel system.
