Weber DCNF/DMTR/DMTL/DCNVA Carburetor Pump Diaphragm

This replacement pump diaphragm is used in the accelerator-pump circuit of compatible Weber carburetors. When the throttle opens, the diaphragm moves fuel through the pump circuit to support transient response and reduce hesitation during rapid throttle application. A hardened, cracked, distorted, or leaking diaphragm can contribute to an accelerator-pump discharge problem, off-idle stumble, or inconsistent enrichment response.

MPN 47407.050 is identified for Weber DCNF, DMTR, DMTL, and DCNVA carburetor applications. The diaphragm has a flanged mounting shape, perimeter mounting holes, and a central actuator assembly visible in the product image. Confirm the replacement profile against the carburetor being serviced before installation, particularly when rebuilding an older or previously modified fuel system.

This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.

Reference/MPN: 47407.050.

What Is Included

One Weber carburetor pump diaphragm, MPN 47407.050
Made in Italy.

Important Fitment Note

Verify the carburetor family and the 47407.050 identification before ordering. Compare the removed diaphragm with the replacement for flange outline, mounting-hole layout, central actuator position and shape, diaphragm seating surface, and any applicable thread or interface details. Family names alone may not confirm interchangeability across carburetor revisions or altered assemblies.

Compare the removed part directly before installation. Confirm that the diaphragm sits flat in the pump housing, the perimeter seals correctly, and the actuator aligns with the original pump mechanism without binding.
