Wacker Neuson 5000159570 Fuel/Water Separator Bowl

The Wacker Neuson Fuel/Water Separator Bowl is a genuine OEM component designed for the G25 series portable generator. This direct-fit replacement seats precisely into the existing fuel/water separator assembly across the full G25 lineup, including skid-mounted, custom, extended run tank, and cold weather configurations. As a genuine Wacker Neuson part, the is manufactured to the same specifications as the original, ensuring correct fit and proper function across every G25 variant it covers.

Key Features

• OEM-Grade Bowl Construction — Formed to the original wall thickness and thread specification, maintaining a leak-free seal against the separator housing under operating fuel pressure.
• Drop-In Compatibility — Threads directly onto the existing separator head without adapter fittings, covering skid-mounted, custom, ERT, and cold weather G25 configurations.
• Broad G25 Series Coverage — Confirmed fitment across the G25 mobile generator family, including multiple skid-mounted variants and cold weather-equipped units.
• Protects Fuel System Integrity — A sound, undamaged bowl is what allows the separator to isolate water and particulates from diesel fuel; a cracked or stripped bowl bypasses this protection entirely.
• Fuel System Safety — A properly sealed separator bowl prevents fuel leaks at the filter housing, an important consideration on generator sets operating in enclosed or semi-enclosed environments.

The fuel/water separator bowl is the transparent or opaque outer shell that encloses the separator element and collects water and sediment drawn out of the diesel fuel supply. It threads onto the separator head to create a sealed chamber, allowing the filter element to trap contaminants before fuel reaches the injection system. When the bowl cracks, strips at the threads, or fails to seal, water and debris can pass through to the engine unchecked — causing injector wear, hard starting, and potential fuel system damage over time.
