Carbureted engines often use low pressure mechanical pumps that are mounted outside the fuel tank, whereas fuel injected engines often use electric fuel pumps that are mounted inside the fuel tank (and some fuel injected engines have two fuel pumps: one low pressure/high volume supply pump in the tank and one high …
Does fuel injection have a accelerator pump?
In a fuel injection system, there is no accelerator pump. In this type of system, the vehicle’s on-board computer senses the need for additional fuel and sends a signal to the fuel injectors to spray more fuel.
Do fuel injected motorcycles have a fuel pump?
Manufacturers didn’t have to work very hard to power a few lights and the ignition, but fuel injection requires pressurized fuel. The easiest way to do that is with a fuel pump, which is typically electrically operated.
What are the signs of a bad accelerator pump?

What is the function of a fuel pump in a petrol pump?
Fuel pumps pump gasoline from the vehicle’s fuel tank to the engine and also distribute fuel under low pressure to the carburetor or to the fuel injection system under higher pressure. Carburetor engines utilize low pressure pumps, which are located outside of the fuel tank.
What is a high pressure fuel pump?
This is a device that serves to compress the fuel that is supplied into the fuel pump in order to increase the pressure. High pressure is needed when injecting fuel directly into the combustion chamber so as to ensure that the engine runs efficiently.
How does main engine fuel pump work?
A fuel pump works to supply a definite amount of fuel to all cylinders irrespective of the load at a correct time interval based on the firing order. The fuel pump providing a high pressure fuel to the injector; which then opens the valve against the spring tension to inject atomized fuel to the cylinder.
Which engine is better carburetor or fuel injection?
So with a carburetor, the best fuel to air ratio for each cylinder is approximated for the best performance. However, carburetors do last longer than fuel injection systems and are favored in motor sports. … The carburetor is currently much less expensive than the electronic fuel injection systems.
Is carb better than fuel injection?
While the carburetor may have been around for over a century, fuel injection is a clearly superior alternative, delivering better power, fuel economy and lower emissions.
Which fuel injection system is best?
