The Wacker Neuson Main Jet is a genuine OEM component designed for PTS4V 100mm/4-inch centrifugal trash pumps and GPS8500 and GS8.5V portable generators with electric start. As a direct OEM part, the is manufactured to the same specification as the original, ensuring the carburetor meters fuel at the correct rate for consistent engine performance. This main jet fits both the PTS4V series and the GPS8500/GS8.5V generator line, making it a versatile service part to keep on hand for mixed fleets. Verify your model number before ordering to confirm compatibility with your specific unit.
Key Features
- Calibrated Fuel Metering Orifice — Manufactured to the original orifice specification so the carburetor delivers the correct air-fuel ratio at all throttle positions.
- Genuine OEM Quality — Sourced directly from Wacker Neuson; identical construction and material grade to the part that came installed at the factory.
- Direct Carburetor Drop-In — Threads directly into the carburetor body the same way the original did, with no re-jetting or adjustment needed beyond standard carburetor service procedure.
- Broad Model Coverage — Fits PTS4V trash pumps and GPS8500/GS8.5V portable generators with electric start, covering multiple machine types with a single part number.
- Protects Engine from Rich or Lean Conditions — A worn or damaged main jet causes poor throttle response, excessive fuel consumption, or lean-running damage; replacing it restores clean combustion and protects engine internals.
The main jet is the precisely sized orifice inside the carburetor that controls how much fuel is drawn into the engine under load. Because the opening is machined to an exact diameter, even minor wear, corrosion, or blockage from stale fuel deposits can disrupt the air-fuel mixture — resulting in hard starting, rough running, power loss, or engine damage from running too lean. Replacing a compromised main jet with a correctly spec'd OEM part restores the carburetor's ability to meter fuel accurately, bringing engine output back to its rated performance level.
