Confirm your machine number against the fitment list before ordering to ensure a direct match.
Key Features
- Exact OEM Electrical Specification — Manufactured to the precise coil resistance and voltage rating required by Wacker Neuson GP and GV series generator fuel systems, ensuring correct actuation every time.
- Direct Bolt-In Replacement — Engineered to the original port size, thread pitch, and connector configuration, so the 5000158529 installs in the same location as the factory unit without modification.
- Broad Generator Family Coverage — Fits GP3800A, GP5600A, GP6600A, GPS5600A, GPS6600A, GV3800A, GV5600A, GV6600A, and GV7000A/GV7003A models across EPA, CARB, CSA, and standard configurations.
- Fuel Flow Control You Can Count On — A correctly functioning solenoid valve opens and closes the fuel circuit on demand; a failed unit can cause hard starting, stalling under load, or a generator that will not run at all.
- Fuel System Safety Compliance — As a fuel-circuit component, using the correct OEM part maintains the integrity of the generator's fuel shutoff system, which is critical for safe operation and transport.
The solenoid valve assembly controls the flow of fuel into the carburetor or fuel circuit by opening when the generator is switched on and closing when it is shut off or loses power — acting as an automatic fuel cutoff. This prevents fuel from flooding the carburetor when the engine is not running, a common cause of hard starting and raw fuel leaks. When the solenoid fails — whether due to a burned coil, stuck plunger, or corroded connector — the engine may refuse to start, run erratically, or shut down unexpectedly under load.
