The fuel pump replacement cost will depend on what vehicle you are driving, car, truck, gasoline or diesel. The main function of the fuel pump is to pressurize the fuel in to the fuel rail so that the injectors can distribute fuel to each cylinder of the engine thus creating power. If the pump fails to hold pressure, the injectors would not be able to give out enough fuel to the engine causing it to stall. Unfortunately, there is no sure way of knowing that your fuel pump is failing until it actually does and it usually involves a tow truck.
Where Is The Pump?
The fuel pump is normally located inside the fuel tank, hence the name “in-tank fuel pump”. I say “usually” because there are some models that have the fuel pump mounted along the fuel lines (external). The in-tank fuel pump is housed in a fuel pump module consisting of the pump, the sock that is a filtration unit, sending unit, which is connected to the fuel gauge in the dash, connectors and the housing. Before looking at your fuel pump replacement cost, here are some of the reasons why a fuel pump fails:
Reasons Why A Fuel Pump Fails
– Dirty fuel may carry contaminants that cannot be filtered by the sock, which then damages the pump.
– Moisture in the tank corrodes the pump and its connectors, which may lead to a short circuit damaging the pump. Some of you might be wondering, “If there is a short circuit in the tank wouldn’t it explode?” The short answer is no. Liquid gasoline does not explode, gasoline mixed with air does but the fuel tank is designed to prevent that from happening.
– Regularly driving with the fuel light on will also shorten the lifespan of the pump.
How Much Am I Looking At?
Again, as I have said earlier, the fuel pump replacement cost will depend on what you have. When replacing the fuel pump, regardless of what your beer-swilling uncle will tell you, contact your local dealership first just to know how much of your arms and legs it will cost to have it replaced. If you do not have any more to spare, then it is time to check out the aftermarket.
There are two ways of fixing a broken fuel pump. You can buy the whole assembly or just the pump itself. Buying the whole thing will cost more but will save you time and effort. On the other hand, getting the pump by itself costs considerably less but will require more time and more work.
What Else Do I Need To Know?
Be sure of what you have. Know your exact year, make, and model. Fuel pumps are vehicle specific and getting the correct part the first time will save you time and money. If you are not sure about the vehicle you are driving, check your VIN. There many websites that offers free VIN decoders. Use them. A little effort can go a long way so that you can keep your fuel pump replacement cost low.
