Walbro Fuel Pump Diaphragm for Small Engine Carburetors

Walbro fuel pump diaphragms are replacement carburetor pump diaphragms for small engines. Walbro has specialized in small engine carburetion since 1950. These diaphragms are used in the pump section of Walbro diaphragm carburetors, the type found on line trimmers, leaf blowers, chainsaws, edgers and similar handheld outdoor power equipment. They are also called carburetor pump diaphragms or fuel pump membranes.

Key Features:

• Replaces the fuel pump diaphragm in the pump side of the carburetor
• Flexes with engine pulses to draw fuel from the tank and push it to the metering side of the carburetor
• Genuine Walbro parts, built to the carburetor maker's original specifications
• Helps restore steady fuel delivery, easier starting and smoother running when an old diaphragm has hardened, stiffened or cracked
• An inexpensive repair that is often done when rebuilding a carburetor

A worn or stiff diaphragm can cause hard starting, rough running or a lean condition. Replacing it is a common part of carburetor service. Check the part number of the diaphragm you need against your carburetor model before ordering.
