A component that plays a vital role in the smooth running of your car is the fuel pump. This article is a quick guide to fuel pumps, their operation, and maintenance.
Where Is the Fuel Pump Located?
The fuel pump is an essential component of your vehicle’s fuel system, responsible for delivering fuel from the tank to the engine at the necessary pressure for optimum performance. In most modern vehicles, the fuel pump is located inside the fuel tank. This placement helps in cooling the pump and ensures a consistent supply of fuel. However, in some older models or specific vehicle types, the fuel pump may be located outside the tank, typically along the fuel line or on the engine block.
Signs Your Fuel Pump Is Going Out
While not exhaustive, these are some key indicators that your fuel pump may be on its last legs:
1.Difficulty Starting the Vehicle: If the car struggles to start (despite a healthy battery), it could be a sign of a failing fuel pump. Vehicle could also stall unexpectedly.
2.Sputtering Engine: A fuel pump that cannot maintain consistent pressure may cause the engine to sputter at high speeds.
3.Loss of Power During Acceleration: If your car loses power while accelerating, especially under stress like climbing hills, this may indicate a problem with the fuel pump.
Recently, in 2020, Honda initiated a recall for around 40,000 of its models in Europe due to problems with the fuel pump impellers. These components were found to have lower density, which could potentially lead to vehicle stalling while driving.
How Do You Tell If Your Fuel Pump or Fuel Filter Is Bad?
Differentiating between a bad fuel pump and a clogged fuel filter can help narrow down the source of the issue as a clogged fuel filter can exhibit similar symptoms to a failing fuel pump. However, a bad fuel filter often results in a lack of power and engine misfires, along with increased fuel consumption. If replacing the fuel filter does not improve the situation, the problem may lie with the fuel pump itself.
How Does a Fuel Pump Work?
A fuel pump works by drawing fuel from the fuel tank and pushing it to the engine under the required pressure. In-tank electric fuel pumps use an electric motor to drive an impeller or turbine, creating pressure in the fuel lines. This pressurised fuel is then delivered to the fuel injection system depending on the vehicle’s design. The pump must provide a constant fuel flow under the correct pressure to ensure the engine runs smoothly across various operating conditions.
What Happens When a Fuel Pump Goes Out While Driving
If a fuel pump fails while you’re driving, the engine will quickly use up the remaining fuel in the injection system and then stall. This sudden loss of power can be dangerous, especially at high speeds or in heavy traffic. Indicators of an imminent fuel pump failure include a loss of power under acceleration, a whining noise from the fuel tank, or difficulty starting the vehicle. If you experience these symptoms, we recommend you get it diagnosed and replaced if needed immediately.
How Much Is a New Fuel Pump?
The cost of a new fuel pump in the USA can vary widely depending on the make and model of your vehicle, averaging around $300+ for the part alone. Labour costs for installation can add significantly to the total expense – closer to the $500+ mark. If you need a fuel pump replacement, input your car reg number and postcode on NINGBO GRANDOTO GROUP and you’ll get a fixed price for the repair.
