Can A Bad Gas Cap Cause Vapor Lock??
What causes vapor lock? Vapor lock happens when the temperature of fuel gets high enough to transform liquid into a vapor state. Fuel pumps are designed to pump liquid, not air, and the increased pressure inside the fuel lines keeps the fuel pump from being able to keep the fuel moving.17.11.2016

Where does vapor lock occur?
Vapor lock is most likely to occur in the fuel injector lines after the flow divider, as fuel is sent to the injector nozzles to be sprayed into the intake manifold. This is because the heat from the engine cylinders and crankcase radiates outwards and up toward the fuel injector lines.03.06.2021
What causes a car to vapor lock?
Vapor lock is caused by heat. Excessive heat from the engine, exhaust system, and/or outside temperature can cause the fuel to vaporize in the lines. Some winter fuel blends and high altitude can lower the boiling point of the fuel. This can also contribute to vapor lock.20.11.2019
