The Wacker Neuson Fuel Water Separator Filter is a genuine OEM component designed for the RD27-100 and RD27-120 series ride-on tandem rollers. As a direct OEM replacement, this filter is sourced to the same specification as the part originally installed at the factory, ensuring correct fit and consistent performance across all RD27 Pro, RD27 Basic, and T4F-compliant variants. Confirmed fitment spans the full RD27 family, covering both the RD27-100 and RD27-120 configurations in Pro and Basic trim levels.
Key Features
- Genuine OEM Filtration Media — Manufactured to the same separation efficiency and micron rating as the original, maintaining consistent fuel cleanliness in the RD27's diesel system.
- Direct Drop-In Replacement — Designed to thread or seat into the existing filter housing on RD27-100 and RD27-120 machines without modification to fuel lines or mounting brackets.
- Broad RD27 Family Coverage — Fits RD27-100 and RD27-120 tandem rollers across Pro, Basic, and T4F emissions-compliant configurations.
- Protects Fuel Injectors and Pump — Separates free water from diesel before it reaches precision fuel system components, preventing corrosion, injector wear, and hard-start conditions.
- Fuel System Safety — Water contamination in a diesel fuel system can cause injector failure or uncontrolled engine behavior; replacing this filter on schedule keeps the fuel supply clean and the engine running as intended.
A fuel water separator filter sits in the diesel fuel supply line between the tank and the injection system, capturing suspended water droplets and particulate matter before they reach the fuel pump and injectors. Water in diesel fuel accelerates internal corrosion, degrades lubrication within the injection pump, and can cause misfires or complete engine shutdown — particularly on hydraulically driven compaction equipment like the RD27, where consistent engine output directly affects compaction performance. A clogged or saturated separator filter restricts fuel flow, causing hard starts, rough running, and potential long-term damage to high-precision fuel system components.
