How a Fuel Pulse Pump Works - It Still Runs

A well maintained pump works at 5,000 pulses per minute. Function. The bottom end of the engine crankcase is continuously subjected to a high or low pressure with every pulse. This pulse is transferred to the fuel pump by a pulse tube. The pulse line connects the pulse chaer. The pressure of the crankcase is pushed by the pulse through a pair

How does a vacuum petcock work? | South Bay Riders

2010-5-6 · Yup it is probably stuck. The way a vacuum petcock works is the vacuum pulls the diaphragm back, compressing a spring and releasing pressure on a ball or some other sort of valve, this allows fuel to flow around the ball and to the carb. Usually vacuum petcocks fail because the diaphragm gets split and/or the vacuum line to the petcock gets

Vacuum Fuel Pump How It Works - SeniorCare2Share

How does a vacuum diaphragm fuel pump work? Diaphragm pumps use a composite merane, which flexes up-down over a fuel bowl. The bowl has an input and an output, each with a check valve in place to ensure a one-way motion of fluid. As the diaphragm moves up, it creates a vacuum, pulling fuel from fuel tank into the fuel bowl.
