If you’re like most people, you probably don’t think about your car’s fuel pump until it stops working. A bad fuel pump can cause all sorts of problems, from a failed emissions test to a stranded vehicle. In this blog post, we will discuss the purpose and function of a fuel pump, as well as some common issues and symptoms of a bad one. We will also cover how long it takes to replace a fuel pump and what the typical cost of this work is.
Before we get into the detail, lets us remind ourselves what exactly a fuel pump does in a car.
What Does A Fuel Pump Do?
The fuel pump is responsible for supplying gasoline to the engine. It draws fuel from the tank and pushes it through a series of hoses and filters to the engine. If the fuel pump stops working, the car will not be able to start or run properly.
The pump is powered by the engine. It is usually located in the gas tank, and it consists of a motor and a pump. The motor draws power from the car’s electrical system, and the pump pushes gasoline to the engine.
How Long Does A Fuel Pump Typically Last?
The average fuel pump lasts about 100,000 miles, but I’ve seen plenty of automobiles with their original fuel pumps functioning well after 200,000 miles. So, why do some fuel pumps live longer than others? There are a variety of reasons. In general, if you use better gasoline and maintain the tank at least a quarter full or more, your fuel pump will last longer. Also, if your car has a fuel filter, be sure to change it as recommended by the manufacturer. A clogged or dirty fuel filter puts unnecessary strain on the fuel pump and can shorten its lifespan.
What Are Some Common Issues and Symptoms Of Failure?
Most car owners are not aware that their fuel pumps can fail. There are many different ways a fuel pump can fail, but there are a few common ways.
1.Not Enough Power
The most common way for a fuel pump to fail is by not getting enough power. This can be caused by a faulty relay or fuse, or even a bad connection.
Symptom: : If your car tends to have a hard time starting. This is usually caused by the pump not getting enough power
2.The Pump Itself is Faulty
Another common way for a fuel pump to fail is by the pump itself going bad. This can be caused by wear and tear, or even contamination.
Symptom: The car starts to run rough (Or doesn’t start at all), this can also be a symptom of a failing or failed fuel pump.
3.Bad Pressure Regulator
A third way for a fuel pump to fail is by the pressure regulator failing. This can cause the pump to either not create enough pressure, or too much pressure. Lastly, the check valve in the fuel pump can fail and cause issues with the pump as well. These are just a few of the most common ways a fuel pump can fail.
Symptom: If your car starts to sputter or stall when you are driving. This is usually caused by not having enough pressure or too much pressure in the system.
Other Symptoms May Include But are not limited to :
-There is a decrease in power and acceleration.
-The car’s fuel economy decreases significantly.
-The car begins to run out of gas more quickly than usual.
-There is an unusual noise coming from the fuel tank area.
What Are The Steps For Replacing A Fuel Pump?
There are a few things to keep in mind before starting this process:
– Make sure your car is turned off and cool to the touch. This is especially important if your car has been running recently.
– Be careful when working around gasoline, as it is a flammable substance.
Basic Tools Required
Removing the fuel pump from a car can be a daunting task. There are many different ways to approach the problem, but these are the basic steps:
- Disconnect the negative battery cable.
- Remove the fuel filler cap and loosen the gas tank lid.
- If you have an electric fuel pump, disconnect the electrical connector from the pump. If you have a mechanical fuel pump, remove the screws that hold it in place and take it out of the tank.
- Screw-in a new fuel pump if you are replacing it, or connect the electrical connector if you are installing a new one. Make sure that any clamps or connectors are tight so there is no leakage.
- Replace the gas tank lid and filler cap, then reconnect the negative battery cable.
- Start the engine and check for leaks.
How Long Does A Fuel Pump Replacement Take?
A car with an external fuel pump can be replaced in an hour or two. However, if you’re replacing the entire fuel assembly and need to drop the fuel tank, this can drive the time up to around 4 or 5 hours. Some other factors which may affect the time required are :
– The make and model of the vehicle
– The year, make, and model of the original fuel pump
– Availability of replacement parts from your auto shop or online retailer (which may have you waiting for a few days)
– Skill level and experience with replacing a fuel pump in specific vehicles. You could reduce this time by searching online for guides to help with this process. Most companies also offer manuals for their cars, which include instructions and illustrations for doing repairs on them, if they don’t use videos. Keep in mind that some repairs are best left to the professionals.
Can You Replace A Fuel Pump Yourself?
Yes, but if you’re not sure of what you’re doing, it’s better to bring the car in for service.
There are various factors that may make this project more complicated, like how old your car is and how much knowledge you have about working on cars in general. If you’ve never replaced a fuel pump before and don’t want to take any chances fixing everything that would go wrong, then it’s best to consult a professional first.
What Is The Typical Cost Of a Fuel Pump Replacement?
The cost of a new fuel pump can vary, depending on the model and make of your car. You can usually find pumps for around $100-$200 online, but they may be more expensive if you need to purchase them from your auto shop. If you’re comfortable doing this repair yourself, you can save some money by finding the right pump and getting the job done without paying an auto mechanic.
Tips For Keeping A Healthy Fuel Pump
-If a car sits for too long, the gas in the tank can evaporate and leave behind a more concentrated, higher-octane mixture. This can cause corrosion and clogging in the fuel pump. To avoid this problem, add a fuel stabilizer to the tank before storage.
-Another way to keep the fuel pump working properly is to use premium unleaded gasoline. The higher octane rating helps prevent knocking and pinging, which can damage the fuel pump over time.
-Finally, make sure to change the engine oil regularly. Dirty oil can gum up the moving parts in the fuel pump, causing it to fail prematurely. By following these simple tips, you can extend the life of your car’s fuel pump
