British Airways Flight 38 crash-landed at London Heathrow in 2008 after its fuel lines became clogged with ice crystals.. In an internal combustion engine, fuel starvation is the failure of the fuel system to supply sufficient fuel to allow the engine to run properly, for example due to blockage, vapor lock, contamination by water, malfunction of the fuel pump or incorrect operation, leading ...
Moving the fuel pump to the interior of the tank helps prevent vapor lock since the entire fuel-delivery system is under positive pressure and the fuel pump runs cooler than it would be if it is located in the engine compartment. This is the primary reason that vapor lock is rare in modern fuel systems. For the same reason, some carbureted ...
The negative pressure created by a vacuum pump typically located in the fuel dispenser, combined with the pressure in the car's fuel tank caused by the inflow, is usually used to pull in the vapors. They are drawn in through holes in the side of the nozzle and travel along a return path through another hose.
Most modern pumps have an automatic cut-off feature that stops the flow when the tank is full. This is done with an auxiliary sensing tube running from just inside the mouth of the nozzle to a Venturi pump in the pump handle. A mechanical valve in the pump handle detects a change of pressure and closes, preventing the flow of fuel. [28] [29]
The reasons that the fuel pump is typically located in the fuel tank are: By submerging the pump in fuel at the bottom of the tank, the pump is cooled by the surrounding fuel; Liquid fuel by itself (i.e. without oxygen present) isn't flammable, therefore surrounding the fuel pump by fuel reduces the risk of fire; In-tank fuel pumps are often ...

A pump stopping; A check valve which closes quickly (i.e., "check valve slam") due to the flow in a pipe reversing direction on loss of motive power, such as a pump stopping. "Non-slam" check valves can be used to reduce the pressure surge.
