The Wacker Neuson Main Jet is a genuine OEM component designed for PTS4V and PTS4V(I) series self-priming centrifugal trash pumps. As a direct factory replacement, this main jet ensures the carburetor delivers the correct fuel-to-air ratio your engine depends on for consistent power output and smooth operation. It is the exact part specified for the PTS4V and PTS4V(I) platforms, giving you confidence that fit and function are dialed in from the moment it's installed.
Key Features
- Calibrated Fuel Metering: — Precision-drilled orifice maintains the exact fuel flow rate the PTS4V carburetor is tuned for, supporting consistent engine RPM and output at the pump.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this main jet carries the correct part number 5200001358 and matches original tolerances without any guesswork.
- Drop-In Carburetor Fit: — Threaded to the same spec as the factory-installed jet, this component seats directly into the carburetor body on PTS4V and PTS4V(I) trash pumps.
- Protects Pump Performance: — A correctly sized main jet keeps the engine running at the fuel mixture needed to drive full pump flow capacity — a worn or blocked jet causes rough running, power loss, and hard starting.
- Fuel System Integrity: — Using the OEM-specified jet prevents lean or rich running conditions that can accelerate engine wear or lead to unplanned shutdowns on the jobsite.
The main jet is a small but critical component located inside the carburetor. Its precisely sized orifice meters the volume of fuel drawn into the engine at mid to full throttle — get the sizing wrong and the engine runs lean or rich, both of which hurt performance and longevity. On a trash pump like the PTS4V, where sustained high-load operation is the norm, a blocked, worn, or incorrectly sized main jet will cause the engine to lose power, run rough, or fail to start altogether. Replacing it with the correct OEM part restores proper fuel delivery and gets your pump back to full working capacity.
