The Wacker Neuson Water Separator Assembly is a genuine OEM component designed for the G1100 Generator. As a factory-sourced part, it is manufactured to the exact specifications Wacker Neuson requires for this machine, ensuring a correct, trouble-free installation. This is the same assembly used in original production, so you can install it with confidence knowing it matches what came out. If you're servicing a G1100 Generator, the is the part number to order.
Key Features
- Genuine OEM Filtration Integrity — Manufactured by Wacker Neuson to the exact separation efficiency and housing tolerances required for consistent fuel system protection on the G1100.
- Direct Assembly Replacement — Supplied as a complete Water Separator Assembly, so all internal components and connection points align with the existing fuel line fittings without adaptation.
- Confirmed Fitment for the G1100 Generator — Verified against the G1100 (model 5100013910), so you're ordering against a known application, not guessing on compatibility.
- Protects Engine Performance — A functioning water separator keeps water out of the fuel supply; a failed or saturated separator allows water ingestion that can cause rough running, power loss, and injector damage.
- Fuel System Safety — Proper water separation prevents contamination events that can lead to uncontrolled engine behavior or hard starting under load — critical on a generator expected to run reliably on demand.
A water separator is a fuel system component that removes water droplets from diesel or gasoline before it reaches the engine. Water enters fuel supplies through condensation, contaminated storage, or handling, and if it passes through to the engine it disrupts combustion, accelerates injector and pump wear, and can cause corrosion inside the fuel system. When the separator element becomes saturated or the housing is damaged, water passes through unchecked, and the symptoms — rough running, hard starting, and power loss — can be mistaken for other faults. Replacing the assembly with a genuine OEM unit restores the fuel system's first line of defense and keeps the G1100 Generator running as intended.
