How does a pump work?
The pump creates a higher pressure in the fuel lines, pushing the gasoline to the engine. The higher pressure raises the boiling point of the gasoline. Placing the pump in the tank puts the component least likely to handle gasoline vapor well (the pump itself) farthest from the engine, submersed in cool liquid.
Is it safe to put a fuel pump in a tank?
Another benefit to placing the pump inside the tank is that it is less likely to start a fire. Though electrical components (such as a fuel pump) can spark and ignite fuel vapors, liquid fuel will not explode (see flammability limit) and therefore submerging the pump in the tank is one of the safest places to put it.
What happens if fuel pressure is too high?
If the fuel pressure is too high, the engine will run rough and rich, not combusting all of the fuel being pumped making the engine inefficient and a pollutant. If the pressure is too low, the engine may run lean, misfire, or stall.
Does an ECU shut off the fuel pump?
This increases the life of the pump, allows a smaller and lighter pump, and reduces the power consumed by the pump. Cars with electronic fuel injection have an electronic control unit (ECU) and this may be programmed with safety logic that will shut the electric fuel pump off, even if the engine is running.
What type of fuel pump is used in a carburetor?
Prior to the widespread adoption of electronic fuel injection, most carbureted automobile engines used mechanical fuel pumps to transfer fuel from the fuel tank into the fuel bowls of the carburetor.

Does a carburetor have a needle valve?
The carburettor admits petrol only as it needs it, through the needle valve in its float chamber (See How variable-jet carburettors work ). While the carburettor is full and the needle valve is closed, no petrol leaves the pump. The diaphragm stays down, and the lever idles up and down.
What is the vent on a fuel tank?
The tank has an air vent - usually a pipe or a small hole in the filler cap to allow air in as the tank empties. Some of the latest systems have a carbon filter , so that fuel fumes do not escape.
How does an electric pump work?
An electric pump has a similar diaphragm mechanism; it is worked by a rod that is drawn into a solenoid switch until it opens a set of contacts to turn off the current. An electric pump has a similar diaphragm-and-valve arrangement, but instead of the camshaft, a solenoid (an electromagnetic switch ) provides the pull on the diaphragm.
What is a petrol filter?
The petrol filter may be a replaceable paper one inside a plastic housing in the fuel line . A pump may include a wire or plastic gauze filter, and sometimes a bowl to catch sediment . The air cleaner is a box fitted over the carburettor air intake, usually containing a replaceable paper-filter element .
