Gasket for Diaphragm pump, Solex carburettor.
Carburettor diaphragm pump seal for classic Porsches with Solex engines. Manufactured to OE geometry, it restores a tight seal between the pump cover and carburettor body, stabilizing injection volume and preventing seepage that can cause flat spots, difficult starting, or fuel odour. It fits directly into the above applications—ideal for carburettor rebuilds or any pump service.

• Function: Seals diaphragm pump cover to carb body; maintains correct pump shot
• Position: Carburettor—accelerator/fuel pump section
• Benefits: Leak-free sealing, consistent tip-in enrichment, OE geometry for easy install

Over time, the diaphragm pump gasket can harden, tear, or deform, leading to small fuel leaks or inconsistent carburettor performance.

Replace the gasket whenever:
• The old gasket appears brittle, cracked, or fuel-soaked.
• You notice inconsistent accelerator pump delivery or hesitation when pressing the throttle.
•  Performing a carburettor rebuild or replacing the pump diaphragm.
•  As preventive maintenance on long-stored vehicles or engines exposed to modern ethanol-blended fuels.

Installing a fresh Gasket ensures a secure seal, stable fuel pressure, and smooth accelerator pump operation — preserving proper drivability and performance in your Porsche 356 or 912.
