Vapor lock often causes a vehicle to fail to start after the driver shuts it off for a few minutes. It also causes cars to stall in slow traffic, when the engine tends to operate at a higher than normal temperature. The condition is caused by the heat in the engine compartment vaporizing the fuel in the fuel pump and lines.Continue Reading
Vapor lock occurs more commonly in carbureted vehicles and in air-cooled engines than in fuel-injection or water-cooled engines. Since the introduction of fuel injectors, most manufacturers have moved the fuel pump from the engine compartment to the fuel tank. Submersing the pump in the tank provides positive pressure in the fuel system and reduces the chances of vapor lock.
Operating a vehicle at a high altitude increases the chances of experiencing vapor lock. At the higher elevation, atmospheric pressure is lower, and the boiling point of gasoline is lower. Ethanol also has a lower boiling point than regular unleaded gasoline, increasing the likelihood of vapor lock.
Vapor lock affects the engines used on lawnmowers and aircraft. A vapor-locked engine in an aircraft can cause a forced landing. To prevent such emergencies in the air, most aircraft engines use fuel with a higher boiling point.Learn more about Doors, Windows, & Locks
Tractor trailer inspection procedures start with the inspector instructing the driver to shut down the vehicle's engine, put the vehicle in neutral and take his foot off the brake.

To find out a particular car's engine type, the driver should know the vehicle identification number, or VIN. The VIN contains 17 characters, and the characters in positions four through nine are the vehicle descriptors, which give information like the car model, body type and engine code. By entering the VIN into an online VIN decoder search tool, a car owner can find the engine type.Full Answer >
To find a Mustang's vehicle identification number, look inside the engine compartment under the fender on the driver's side of the vehicle or inside the car just above the dashboard. Additionally, check the data plate on driver's side door, or find the partial VIN on the back of original engine.Full Answer >
