Car Fuel Pump
Majority of the modern vehicles that use internal combustion engines provide with fuel pumps. The fuel pump is the component that is providing fuel from the gas tank to the the engine at the correct pressure need to meet performance demands. When the key is turned on, the fuel pump is working and pressurized, which can be heard as a quiet whine in some cars. The fuel pumps equipped on most modern vehicles are electric pumps that are fitted in the fuel tank. Some vehicles are supply with inline or mechanical style fuel pumps because the fuel pump is the component that supply the engine with the fuel required for it to work.
Malfunction fuel pump can affect the performance therefore when you notice that fuel pump is damage ,you need to get it replace.
There are some sign you can take note of fuel pump starting to spoilt.
1. Loud Whining sound from the fuel tank
One of the first sign of a problem with the fuel pump is a loud whining sound. An old or worn fuel pump may produce a noticeably loud whine sound when it is running. Most fuel pumps will produce a quiet hum during their normal operation.
2. Hard to start
Another sign is usually accompany with a problematic fuel pump is hard to start a car . Because of how they operate (continual running whenever the ignition is turned on) over the period of time, the fuel pumps can eventually wear out and weaken. A weak fuel pump may still pump fuel but the vehicle may encounter hard to starting as a result of the insufficient in pressure. A weakened fuel pump can cause the vehicle to take more cranks to start than usual, and in more serious cases may even result the vehicle to require many turns of the key.
3. Misfires and a decrease in power, acceleration, and fuel efficiency
Another sign is the fuel pump engine performance problem. As the fuel pump is what supplies the vehicle with the fuel demand for combustion to occur, any problem with it can affect the engine’s fuel supply and cause issues. A malfunction fuel pump with low pressure will disrupt the engine’s air-fuel ratio, which can cause all sorts of performance problems such as hard starting, the vehicle may experience a low power and acceleration , low in fuel efficiency and engine stall.
