The upward movement in the diaphragm pushes the fuel up which triggers the inlet to close an outlet valve to open up. The fuel through the outlet valve goes for the carburetor.
A fuel method can have very good tension but not sufficient fuel movement to run the engine thoroughly at better speeds. Flow charge might be analyzed by disconnecting the fuel source line at any hassle-free place and attaching a hose that brings about a measuring container.
