Pump Diaphragm Pierburg Solex 31 PICT 4
This pump diaphragm is used in the accelerator-pump circuit of Pierburg/Solex 31 PICT 4 carburetors. When the throttle opens, the diaphragm displaces fuel through the accelerator-pump passage to support transient response and reduce hesitation during initial acceleration. A worn, hardened, split, or leaking diaphragm can weaken the pump shot and contribute to throttle-opening stumble.
MPN 3262 identifies this diaphragm for fitment verification. Service replacement is appropriate when the existing diaphragm no longer seals correctly or when the accelerator-pump circuit is being inspected during carburetor overhaul.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: 3262.

Important Fitment Note
Verify the carburetor family and confirm the 31 PICT 4 identification before ordering. Check the MPN or marking against 3262, then compare the replacement with the removed diaphragm for outline, mounting-hole pattern, central actuator/stem arrangement, retaining interface, and seat style. Where applicable, verify any thread or fastener interface used by the accelerator-pump assembly.
Compare the geometry and actuator interface with the removed part before installation.
