About this product

The Diaphragm (#22303-47010) is a crucial engine-fuel part in the Pneumatic Governor system of a Toyota vehicle. It primarily functions as a regulator, controlling the flow of fuel to the engine based on the air pressure changes in the intake manifold. This sophisticated system involves several components, including a spring mechanism that works in concert with the diaphragm to balance fuel delivery. Like any auto part, the diaphragm’s performance can deteriorate over time. An old, clogged, or non-functional diaphragm can lead to irregular fuel flow, causing your engine to misfire or even stall. Therefore, regular replacement of the diaphragm is essential. Opting for genuine Toyota parts not only maintains vehicle compatibility but also benefits from Toyota's genuine parts warranty. The efficient function of the diaphragm contributes significantly to the overall performance of your vehicle by ensuring the precise fuel-air mix for optimal combustion, thereby enhancing both efficiency and safety.
