Description

What is the function of fuel injection pump?
The fuel injection pump draws fuel from a fuel tank and pumped it at high pressure to all injectors. In an electronic fuel injection system, the fuel injection pump is used only for pressurizing the fuel line. 2] Metering of the fuel: The inline fuel injector pump helps to control the amount of fuel to be supplied to the injector.

What is the size of a fuel pump and injector?
Size A fuel injector is usually three to four inches long with a diameter of one to two inches. An in-the-tank fuel pump is usually five to seven inches long with a diameter of four to five inches. A fuel pump pressurizes fuel and sends it through the fuel line to the fuel injectors.
How to tell if fuel injection pump is bad?

Some of the faulty fuel injection pump symptoms are as follows:-

1. Engine splutters: The improper fuel injection because of the faulty fuel injection pump is one of the reasons for the sputtering noise of the engine. One can notice this sputtering noise while accelerating the vehicle or at a higher engine speed.

2. Whining noise: This is another symptom that you can hear a whining noise made by the fuel pump at the location of the fuel tank.
It may arise due to the faulty fuel injection pump or it may cause due to the insufficient amount of fuel in the tank, thus it becomes difficult for the pump to suck the fuel.

3. Lack of power when a vehicle is loaded: In some cases when the vehicle is in loaded condition, the fuel pump is not able to provide a sufficient amount of the fuel for the combustion, thus it feels like the engine is unable to produce a sufficient amount of power to move the load.

4. Difficult to start: Sometimes it becomes difficult to start the engine, as the fuel pump is not pressurising the fuel line. In some cases, the engine gets started, and then it again stalls.

5] Smoky exhaust and less fuel economy: One of the reasons behind the smoky exhaust is that the fuel pump is supplying excessive fuel to the injectors. Thus due to the improper combustion of the fuel, smoky exhaust gases are observed at the tailpipe or the fuel economy gets lowered.
