Among many auto parts, the fuel pump is inconspicuous, but it is an important part of ensuring the normal operation of the engine. It can be said that without an efficient fuel pump, even the most high-end engine cannot achieve its due performance. Because of this, the right choice for your car fuel pump is particularly important.

As the "heart of the engine", the fuel pump is responsible for delivering gasoline from the fuel tank to the engine room, and after being atomized by the injection system, it burns to push the piston to run. Once there is a failure or aging phenomenon, it may cause problems such as power drop or even flameout-these problems will undoubtedly seriously affect the driving experience and driving safety.

There are two mainstream types of fuel pumps available for consumers to choose from: mechanical fuel pumps and electric fuel pumps. The former is usually applied to the early traditional internal combustion engine models, relying on the crankshaft to drive the operation; the latter is the standard configuration of modern cars, using electric drive to complete the suction process.
How it works:

• The mechanical fuel pump is connected to the camshaft or other moving components through a linkage mechanism to produce a reciprocating action to achieve the purpose of conveying liquid;
• The electronic control unit (ECU) accurately adjusts the current intensity to change the motor speed and then affect the flow rate to adapt to the amount of fuel required under different working conditions.

So how do you know if your car needs a new fuel pump? The answer is simple-just pay attention to the following typical symptoms to make a preliminary judgment:

1. suddenly acceleration is weak or start-up is difficult;
   if you find that the normally smooth operation is now slow and laborious, it is probably the result of lack of enough pressure.
2. frequent breakdown warning lights are on to indicate abnormal conditions;
   when the relevant indicators on the dashboard are on, it means that there may be hidden dangers in some places that need to be investigated and repaired, including fuel supply devices that may be damaged and failed.
3. when you smell the strong pungent smell overflowing into the surrounding environment of the car space, look for the source of the leak and confirm whether it comes from the cracks and loopholes in the area near the interface of the damaged pipeline. factors such as the occurrence of the leak have aggravated the risk of the leak. the deterioration trend is obviously increasing. the frequency is accelerating. the serious consequences are difficult to predict and cannot be ignored. the timing of the delay is too slow to repentant.
