Sierra Marine Fuel Pump Diaphragm for Yamaha Outboard Motors

Sierra marine fuel pump diaphragms are replacement diaphragms for the mechanical fuel pumps on Yamaha outboard motors. The diaphragm moves fuel from the tank to the engine. A worn, cracked or stiff diaphragm can cause hard starting, fuel starvation, rough running or loss of power. Replacing it restores smooth fuel delivery.

Key Features:

• Aftermarket replacement diaphragm for Yamaha outboard fuel pumps
• Made for marine use and compatible with marine fuel blends
• Helps restore proper fuel pump pressure and flow
• An affordable way to rebuild a fuel pump without replacing the whole assembly
• Backed by Sierra, a long-established supplier of marine engine parts

Sierra designs its marine replacement parts to meet or exceed OEM specifications. Replacing the diaphragm as part of routine fuel system maintenance helps keep your outboard running reliably. Select the correct part number from the options listed for your engine.
