Dellorto 40/45 DHLA Carburetor Pump Diaphragm 7515
This replacement diaphragm is used in the accelerator pump circuit of Dellorto 40/45 DHLA carburetors. The pump diaphragm transfers mechanical movement into a controlled fuel discharge during throttle opening, supplying transient enrichment before the main circuit can respond to the increased airflow.
A worn, hardened, distorted, or damaged diaphragm can contribute to accelerator-pump hesitation, an off-idle flat spot, weak fuel discharge, or inconsistent throttle response. MPN 7515 Use this part during carburetor service when the pump circuit requires a replacement diaphragm or when the existing diaphragm no longer seals and flexes correctly.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: 7515.
What Is Included
- Dellorto DHLA carburetor pump diaphragm, MPN 7515
- Made in Italy.
Important Fitment Note
Verify the carburetor family and the marking before purchase. Confirm that the existing part is used in a Dellorto 40/45 DHLA accelerator-pump assembly, then compare the diaphragm’s outer shape, mounting-lug pattern, central actuator interface, seating surface, and any locating features with the removed part.
Compare the original diaphragm and pump cover before installation; code 7515 alone should be matched with the correct DHLA pump geometry and interface.
