Information
Pump jet (GP) 50 for Solex 40 PII-4 carburetor.
This jet controls the volume of fuel delivered under pump or transition circuits, ensuring correct mixture strength during acceleration or high-demand engine conditions. By matching the original dimensions, flow bore and material characteristics, this replacement part maintains factory-style calibration and helps ensure consistent drivability and fuel metering.
Sold each, 4 required per vehicle.
Fits:
Porsche 356 (Model: CARRERA 1600 GS/GT, 6922) 1950 - 1959
Porsche 356 (Model: CARRERA 1500 GS/GT, 40 PII-4) 1950 - 1959

Diagram ref no 16
• Function: Regulates fuel flow through the pump / transition circuit in the carburetor
• Position: Within the carburetor body, pump / high-demand fuel circuit
Over time, metering jets like the pump jet may suffer from erosion, corrosion, or deformation, especially due to fuel additives or long‐term use. A worn or mis-sized jet can lead to rich/lean conditions, hesitation, flat spots during acceleration, or unstable mixture transitions.
Replace this jet when:
• You are performing a full carburetor rebuild or overhaul
• Your engine shows hesitation, poor acceleration or throttle flat spots
• The original jet is missing, damaged, or shows signs of internal wear.
• You want to restore factory-correct fuel metering for reliable classic Porsche performance.
Installing a new Pump Jet ensures accurate fuel delivery, consistent mixture behaviour and helps maintain the authentic feel and smooth acceleration of your classic Porsche.
