It is a calibrated part from 0 to 100. The larger the number the more fuel is bled back to the float chamber when the pump jet is operated. The size used depends on the pump rod length \u0026amp; pump jet size. The 'zero' valve is often used to eliminate 'flatspots' under acceleration \u0026amp; used widely in competition applications. Sizes vary from 0,35,40,45,50,60,65,70,75,80,90 \u0026amp;100.\u003c\/p\u003e\n\u003cp\u003ePlease give the size you require at checkout.\u003c\/p\u003e\n\u003cp\u003eThis part is often overlooked with calibration \u0026amp; should be checked on removal to ensure the sealed ball inside is moving freely.
