Dellorto 40/45 DHLA Carburetor Pump Diaphragm 9667 Red Double Layer
Type 9667 is the identifying specification for this DHLA pump diaphragm. A hardened, torn, swollen, or incorrectly seated diaphragm can cause a weak accelerator-pump shot, hesitation during throttle application, fuel leakage around the pump cover, or inconsistent enrichment. During service, inspect the pump cover, seating surface, actuator contact area, and related check-valve passages before installation.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: 9667.
Technical role: Type 9667 red double-layer diaphragm for the accelerator pump of Dellorto 40/45 DHLA carburetors.
Service relevance: Replace a hardened, torn, swollen, or incorrectly seated diaphragm that may cause a weak pump shot, throttle hesitation, or fuel leakage at the pump cover.

- Genuine Dellorto DHLA type 9667 red double-layer pump diaphragm

Important Fitment Note
Verify the carburetor family as Dellorto DHLA and confirm the 9667 code or equivalent marking before purchase. For 40/45 DHLA applications, compare the replacement diaphragm with the removed part for overall outline, mounting-hole pattern, central actuator geometry, seating surface, and pump-cover interface. Where a retaining fastener or threaded actuator interface is involved, verify the thread and contact arrangement against the original assembly.
Compare the removed diaphragm and pump cover before installation; similar-looking DHLA diaphragms may differ in seating or actuator geometry.
