Weber 40 DCOM Carburetor Pump Diaphragm – 47407.267D
Key technical facts: Replacement pump diaphragm for Weber DCOM carburetors, identified by part number 47407.267D and reference number 47407.267. This diaphragm operates in the carburetor’s accelerator-pump circuit, flexing with throttle movement to control the additional fuel required during rapid opening. It is separate from the main circuit and is directly relevant to transient response, throttle hesitation, and stumble during acceleration.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: 47407.267D.
What Is Included
- One Weber DCOM carburetor pump diaphragm
- Made in EU.
Important Fitment Note
Verify the carburetor family as Weber DCOM and compare the identification marking with part number 47407.267D / reference number 47407.267. Check the diaphragm’s outside profile, mounting-hole pattern, central actuator or retainer arrangement, and any applicable thread, seat, or interface details against the removed part and the pump cover. Compare the new diaphragm directly with the removed part before installation; visual similarity alone does not confirm compatibility.
