Diaphragm For Fuel Pump.
Restore reliable fuel delivery with this OE Match Fuel Pump Diaphragm. Produced to OE-style specifications, this diaphragm is designed for compatible mechanical fuel pumps, providing the flexible sealing membrane required to pump fuel efficiently from the fuel tank to the engine. Manufactured from high-quality, fuel-resistant rubber reinforced for strength and durability, it offers excellent resistance to modern fuels, heat, and continual flexing, making it ideal for Porsche maintenance, repairs, and restoration projects.

Fits:

• Porsche 356 1950-55
• Porsche 356A 1955-59
• Porsche 356B 1959-63 

 
Diagram Ref No 20

The fuel pump diaphragm is the heart of a mechanical fuel pump, moving back and forth with engine operation to generate the vacuum and pressure required for continuous fuel flow. Over time, constant movement, age, fuel additives, and heat can cause the diaphragm to harden, crack, stretch, or split, reducing pump efficiency or causing complete fuel delivery failure. Replacing a worn diaphragm restores dependable fuel supply while extending the service life of the original fuel pump.  

What This Product Does:

• Generates suction and pressure within the mechanical fuel pump.
• Draws fuel from the tank and delivers it to the engine.
• Maintains consistent fuel flow under varying engine speeds.
• Provides a fuel-tight internal seal within the pump.
• Supports reliable engine starting and smooth operation.
• Replaces worn, cracked, or damaged fuel pump diaphragms.
• Provides an OE-style fit for straightforward installation.

Symptoms Of Wear Or Failure:

• Difficulty starting the engine.
• Loss of fuel pressure.
• Engine hesitation or misfiring.
• Poor acceleration or reduced engine performance.
• Fuel leakage from the mechanical fuel pump.
• Cracked, hardened, or split diaphragm during pump overhaul.
• Engine stalling caused by inadequate fuel delivery.

Why Replacement Matters:

• The fuel pump diaphragm is the primary pumping element within a mechanical fuel pump and is essential for maintaining consistent fuel delivery to the engine. As the diaphragm ages, continual flexing and exposure to fuel can cause deterioration, reducing fuel pressure and affecting engine performance. If the diaphragm fails completely, fuel delivery may stop altogether, preventing the engine from running.
• Replacing a worn diaphragm restores the performance of the mechanical fuel pump, ensuring reliable fuel flow, smoother engine operation, and improved starting performance while preserving the original fuel pump assembly. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Fuel Pump Diaphragm provides reliable fit, performance, and durability for Porsche maintenance, repairs, and restoration projects.
