The Wacker Neuson Fuel Solenoid is a genuine OEM component designed for PTS4V series centrifugal trash pumps and GPS8500 / GPS9700 series portable generators. As a direct factory replacement, this solenoid maintains the precise electrical and fuel-control characteristics the engine management system requires. It is also confirmed to fit the GS8.5V and GS9.7V generator models, making it a versatile service part across Wacker Neuson's pump and power equipment lines. Order with confidence knowing this is the same part originally installed at the factory.
Key Features
- Correct Coil Resistance and Valve Timing — Genuine OEM construction ensures the solenoid opens and closes at the exact voltage and response speed the engine control circuit expects, preventing hard starts and rough running.
- Direct Plug-In Replacement — Connector, thread pitch, and body dimensions match the original mounting position, allowing a straightforward swap without modifying fuel lines or wiring harnesses.
- Broad Fitment Across Two Equipment Families — Confirmed for PTS4V and PTS4V(I) 100mm/4-inch trash pumps and GPS8500, GPS9700, GS8.5V, and GS9.7V portable generators.
- Protects Engine From Fuel Run-On — A properly functioning fuel solenoid cuts fuel flow the moment the ignition is switched off, preventing diesel run-on and uncontrolled engine operation.
- Fuel System Safety — A failed or stuck-open solenoid can allow uncontrolled fuel delivery; replacing a worn unit with a genuine OEM part restores proper shut-off function and reduces the risk of fuel system hazards.
A fuel solenoid is an electrically operated valve that controls the flow of fuel to the engine's carburetor or injection system. When the ignition is switched on, the solenoid energizes and opens, allowing fuel to reach the engine; when the ignition is cut, it de-energizes and closes, stopping fuel flow immediately. A faulty solenoid can cause symptoms ranging from failure to start and intermittent stalling to the engine continuing to run after the key is turned off — all of which point to the need for a direct replacement like the Wacker Neuson 5000084045.
