7/14/2023 0 Comments Fuel vapor lockYou shouldn’t pour cold water for a longer time as it may result in engine-related problems. It will also eliminate vapor blockage in the lines and fuel pump.Īfter pouring the cold water, you should wait for some minutes before turning on the ignition. Cold water will help in the faster liquefaction of the vapors. Before doing this, you should ensure that the ignition system is off. You can cool down the system by pouring cold water on the fuel pump. Here are some of them: Cool Down the Fuel Pump There are several techniques that you can use to fix a vapor lock. Does the warm engine stall and doesn’t start until it cools?.Does the condition only happen when driving under hot conditions?.Does the engine stumble or hesitate when it warms up?.When this happens, a vacuum is created in the fuel line, making fuel more disposed to vaporization under high engine temperatures. On the other hand, many carbureted engines use a mechanical fuel pump to pull fuel out of the tank to feed the engine. Modern engines are also equipped with an electric cooling fan hence, it is more difficult for vapor bubbles to form in the fuel lines under high operating temperatures. Additionally, fuel is pressurized in a modern fuel delivery system.Ĭheck this too: Why is My Coolant Level Dropping? At the same time, it’s immersed in fuel and a lower temperature compared to the older mechanical pump located in the engine compartment. This technology allows the pump to operate at a low point in the tank. Vapor lock is less prevalent in modern engines because they use in-tank, electric fuel pumps. The problem is also common when a vehicle has been idling or turned off and then back on. Vapor lock is more common in older car models however, it became more predominant in carbureted engines with the appearance of the modern fuel injection system. When it happens, it disrupts the correct air to fuel ratio and prevents fuel from reaching the specific fuel lines, resulting in engine stops. Vapor lock happens when fuel overheats and turns to vapor in a fuel injector, fuel line, or carburetor.
