OE Match

Diaphragm for Solex 40PII-4 carburettor.
This diaphragm is manufactured to match Porsche OEM specifications, used in the carburettor/fuel pump assembly of early Porsche models such as the 356 B/C and 912 (Solex 40 PII-4 systems). This diaphragm ensures correct movement of the pump or fuel-metering circuit, maintaining consistent fuel delivery, avoiding starvation under load, and preserving the original throttle response characteristics. 

Fits:
Porsche 356B / 356C (Model: 1600 S90/SC, CARRERA, 587/1 692/3A) 1960-1965
Porsche 912 1.6L 1965 - 1969 (Engine code: 616/36/37)
Porsche 912 1.6L 1965 - 1969 (Engine code: 616/39/40)

Diagram ref no 64

• Function: Flexes to actuate fuel-pump or carburettor component; maintains consistent fuel flow and pressure
• Position: Inside carburettor body or fuel pump assembly
• Benefits: Exact fit geometry, reliable sealing, restores factory fuel-delivery behaviour
• Installation: Replace during carburettor rebuild or fuel-system service; Ensure correct mounting orientation and inspect surrounding seals/gaskets.

Diaphragms in carburettor or fuel-pump assemblies are subject to continuous flexing, contact with fuel/ vapour, and ageing of elastomer materials. Over time the diaphragm may become hardened, cracked, or leak, leading to inconsistent fuel delivery, hesitation under acceleration or poor idle.

Replace this diaphragm when:
• Performing a carburettor rebuild, fuel-pump service or full engine commissioning
• The existing diaphragm shows visible cracks, deformation, fuel seepage or stickiness
• You experience fuel starvation, erratic throttle response or tuning instability
• You’re restoring your classic Porsche engine to factory-correct performance

Installing a new diaphragm restores correct actuation, sealing and fuel-flow behaviour—ensuring your induction system runs true, smooth and as intended.

Porsche 912 1.6L 1965 - 1969  (Engine code:  616/39/40)

Diagram ref no 46

Manufactured to replicates Porsche’s original geometry and sealing quality. It’s ideal for carburetor rebuilds, tuning, or replacing worn valves that cause flooding, lean conditions, or erratic mixture balance.

• Function: Regulates fuel entry to float bowl by closing inlet as float rises
• Fitment: Porsche 356 B/C and 912 with Solex 40 PII-4 carburetors
• Position: Inside float chamber cover (fuel inlet port)
• Flow Size: 1.75 mm – OE spec calibration
• Benefits: OE-style geometry, precise fuel control, leak-free sealing, reliable idle and acceleration
• Installation: Replace valve during carb rebuild; verify float height and seal tightness

Float valves wear naturally from constant fuel pressure, vibration, and ethanol exposure. As the tip or seat degrades, it can cause fuel overflow, hard starting, or lean running.

Replace this part when:
• Rebuilding the carburetor or adjusting float levels
• You notice fuel leakage, overflow, or inconsistent idle
• The needle shows grooves or corrosion on the tip
• Restoring carburetors to factory spec for balanced mixture control

Installing a new Float Valve ensures accurate bowl levels, steady fuel flow, and reliable operation of your classic Porsche 356 or 912’s Solex carburetors.
