The Wacker Neuson 5000159088 is a genuine OEM Fuel/Water Separator designed for a broad range of Wacker Neuson G25 portable generators, LTW light towers, HI indirect-fired air heaters, and PT6 trash pumps. As a direct OEM replacement, the part is manufactured to the same specifications as the original component, ensuring a correct fit within the fuel system it was engineered for. This separator is confirmed compatible across multiple equipment families including G25, LTW6K, LTW8K, LTW20Z-1, LTW20Z-3, HI750, HI900, HI260, PT6LT, and PT6LS series machines. Stocking this part means your equipment stays protected and your fuel system operates as designed.

Key Features

  • Genuine OEM Filtration Performance — Manufactured to original specification, this separator delivers the same water-separation efficiency and particulate protection as the part it replaces, keeping contaminants out of injectors and fuel system components.
  • Direct Drop-In Replacement — Designed to connect to existing fuel lines and mounting points without modification, this part installs exactly where the original unit was fitted.
  • Broad Cross-Family Compatibility — A single part number covering G25 generators, LTW6K, LTW8K, LTW20Z-1, and LTW20Z-3 light towers, HI750, HI900, and HI260 indirect-fired air heaters, and PT6LT and PT6LS trash pumps — verify your machine number before ordering.
  • Protects Downstream Fuel System Components — By separating water and trapping particulates before they reach the fuel injectors or pump, a properly functioning separator prevents costly internal damage and unplanned engine failures.
  • Fuel System Safety — Water intrusion in diesel fuel systems can cause misfires, injector corrosion, and uncontrolled fuel delivery; replacing a degraded separator at the correct service interval supports safe, stable operation of generator, lighting, and heating equipment on the worksite.

A fuel/water separator removes water droplets and fine particulates from diesel fuel before it reaches the engine's injection system. Water contamination in diesel can cause corrosion of precision injector components, loss of lubrication within the fuel pump, and inconsistent combustion — all of which lead to rough running, hard starting, or engine damage. When the separator element becomes saturated or the housing cracks, unfiltered fuel passes directly into the system; replacing the separator at the recommended service interval is one of the most straightforward ways to protect the engine and extend the service life of generators, light towers, heaters, and pumps that depend on clean fuel delivery.
