• Installed an external vacuum petcock between carburetor and a modified air intake on a motorbike, so the setup is such that fuel cannot not enter the carburetor until engine is cranked. The modified air intake manifold has a vacuum pipe attached to the petcock’s air inlet, which will pull down the diaphragm and allow the fuel to flow from fuel-tank to the carburetor and ultimately resulting the air fuel mixture to enter the combustion chamber.

• Hence, this system will allow the fuel to flow into the engine when the engine is cranked, thus avoiding fuel leakage and theft of fuel when the engine is shut off.

• Worked on this project to avoid fuel leakage and theft of fuel from motorbike.
