By replacing the worn-out or damaged diaphragm with a new one, you can help restore your Volvo's fuel system to optimal condition, ensuring a smoother, more reliable driving experience.

In summary, the Volvo B18 20/30 engine carburetor diaphragm, part number 237666-3, is a vital component that helps maintain the proper fuel pressure in your Volvo's engine.
