This is a carburetor diaphragm, which is an OEM part that pumps fuel from the tank to the engine. It is roughly 1x2 inches and black in color. Sold individually, this part can fail due to fatigue and wear, and if it is broken you may notice your engine is running rough or not starting. If your engine exhibits these signs of being starved of fuel, your diaphragm is damaged and needs to be replaced.
Our customers found this repair to be of medium difficulty. It requires a wrench, screwdriver, and pliers to complete. You will be able to locate your diaphragm inside the carburetor itself to swap it out with your new one.

Little rubber thingy
First time I ever took a carb apart . Matched it up , ordered it . It went back together easily. Then fired up on 2nd pull. Works great . Slow on the shipping , but works great !

Carb diaphram
The part fit nicely on an old motor that I thought might be unrepairable. I still had to fix the spark, but runs good now.

Replace fuel diaphragm, fuel pickup tube and air cleaner
This 5hp B&G was manufactured in 1985! Had been garage kept and always dependable. After 10 years of non use the carb wasn't getting gas. Removed air cleaner box, muffler and crankcase breather to easily remove carb, replace parts and reassemble.
