The fuel pump is a critical component of a car, delivering fuel from the tank to the engine. It is typically located inside the tank, submerged in fuel, which helps to cool and lubricate it. When the fuel tank is running low, the pump has to work harder to extract fuel from the bottom of the tank, leading to premature wear and tear. To maintain your car's fuel pump, it is important to keep the fuel tank full and avoid contamination by filling up at newer gas stations. Additionally, consistent engine temperature and the use of a fuel pressure gauge can help diagnose and address issues with the fuel pump.

Keep your fuel tank full to avoid overworking the pump
Keeping your fuel tank full can significantly impact the performance and longevity of your fuel pump. While it may be tempting to push it when your gas light comes on, doing so can put unnecessary pressure on your fuel pump.
The pump is typically submerged in fuel, which cools and lubricates the mechanism. However, when fuel levels are low, the pump has to work harder to extract fuel from the bottom of the tank, and the lack of surrounding fuel can cause the pump to overheat. Over time, this can lead to premature wear and tear on the fuel pump.
Additionally, a nearly empty tank can increase the risk of sediment build-up. As the fuel pump sucks in the remaining fuel, it can also draw in sediment that has settled at the bottom of the tank. This sediment can clog the fuel pump and potentially harm your engine.
By keeping your fuel tank full, you can prevent these issues and ensure your fuel pump operates efficiently. It may be a heavier haul, but it is a more efficient option in the long run. It helps to maintain the health of your fuel pump and engine, reducing the likelihood of mechanical issues such as engine failure, overheating, and corrosion.

Avoid old gas stations with dirty and/or rusty tanks
While maintaining your car's fuel pump, it is imperative to avoid old gas stations with dirty and/or rusty tanks. Gas stations with rusty and leaky storage tanks pose a significant environmental and health hazard. The steel tanks and piping installed beneath these old gas stations corrode over time, leading to cracks and holes through which petroleum can seep into the surrounding soil and groundwater. This contamination carries carcinogens, such as benzene, which can cause serious health issues for nearby residents and employees.
The environmental impact of these leaky storage tanks is staggering, with a $20 billion cleanup cost nationwide. Even with remediation efforts, some sites remain highly polluted, exceeding state allowable limits for gasoline-related compounds. The contamination can extend to neighbouring properties, affecting not only the soil but also septic tanks and groundwater.
To avoid contributing to this issue, it is advisable to refrain from patronising old gas stations with visibly rusty or poorly maintained tanks. By choosing newer stations with well-maintained infrastructure, you can reduce the risk of exposing your vehicle's fuel pump to contaminated gasoline, which could lead to premature wear and tear.
Additionally, it is worth noting that some gas stations may have hidden contamination issues that are not immediately apparent. If you suspect a particular station may have outdated or poorly maintained tanks, it is prudent to research its history or look for alternative options with better-maintained facilities. Taking proactive measures to avoid potentially contaminated gas stations can help protect your vehicle's fuel pump and contribute to a more sustainable environment.

Replace fuel filters annually to prevent debris from entering the pump
To maintain your car's fuel pump, it is important to replace your fuel filters annually to prevent debris from entering the pump. This is because the fuel filter's job is to filter dirt and prevent impurities that may be in the tank from reaching the engine. If the filter is clogged, it will need to be changed quickly. The presence of water in the fuel system can also have serious consequences, as it can lead to the clogging of injectors.
Depending on your car model, the fuel filter may be mounted inside the tank with the fuel pump and may not need to be replaced. You should always refer to your owner's manual for guidance on whether and how often to change your fuel filter. On average, it is recommended to replace the filter every two years or 30,000 miles. However, it is also important to replace the filter if it starts causing issues or if you put the wrong fuel in your tank.
If you decide to replace the fuel filter yourself, you will need to take certain precautions. First, allow the fuel to drain out by gently twisting and removing the filter. Clean in and around the filter head, then screw the new filter into place, attaching any fuel pipe connections as required. Replace the cover and fasteners, being careful not to damage them. Once you have completed the filter change, you should consider the proper disposal of your old filter, as it is classified as hazardous waste.
Alternatively, you can seek the services of a mobile car battery replacement service or a trusted garage to replace the fuel filter for you. The cost of replacing a fuel filter typically ranges from £25 to £100, depending on the filter quality and the hourly rate of the garage.

Avoid filling up at a station while it's being refuelled by a delivery truck
Maintaining your car's fuel pump is essential to ensure the longevity of your vehicle. One common question that arises is whether it is safe to fill up at a gas station while it is being refuelled by a delivery truck. While modern filtration systems have improved, here are some reasons why you should avoid filling up at a station during refuelling:
Stirring Up of Particulates: When a delivery truck refuels the underground tanks at a gas station, the process can stir up particulates, sediment, and debris at the bottom of the tanks. These contaminants can then get mixed into the fuel that is dispensed into your vehicle. While gas pump filters are designed to capture these particulates, they may not catch everything, potentially leading to issues with your car's fuel system.
Water Contamination: In addition to particulates, water contamination can also occur during the refuelling process. Water can accumulate at the bottom of the tanks, and when the fuel is pumped in, it can get stirred up and enter the intake pipes. While some filters can detect and mitigate water contamination, it is still a risk factor to consider.
Old or Clogged Filters: Not all gas stations maintain their equipment regularly, and old or clogged filters may not effectively capture particulates and contaminants. This can increase the chances of these impurities ending up in your fuel system, potentially causing issues down the line.
Safety Concerns: While it may be a rare occurrence, there are safety concerns associated with refuelling during a delivery truck's presence. Any issues with the hoses, such as leaks or spills, can result in an unsafe situation for customers. It is always better to err on the side of caution and avoid any potential hazards.
By avoiding filling up at a station while it is being refuelled by a delivery truck, you can reduce the risk of contaminating your fuel system with particulates, sediment, or water. This simple precaution can help maintain the health of your car's fuel pump and engine, ensuring a smoother driving experience.

Listen for a loud whining noise, a sign of a bad fuel pump
A failing fuel pump can cause a loud whining noise in your car. This noise is a good indicator that your fuel pump is on its way out and will soon need to be replaced. The whining noise is caused by a low-pressure fuel pump located inside the fuel tank. As the pump starts to fail, it will create this noise, and the vehicle may continue to run for months, or it may fail soon after the noise starts.
If you hear this noise, it is recommended to take your car to a dealer or a shop to have the fuel tank lowered and the pump replaced. This can cost around $500. It is safe to drive the car to the dealer or shop, but it is important to get the pump replaced as soon as possible, as a failing fuel pump can lead to premature wear and tear.
To prevent premature wear and tear on your fuel pump, it is important to keep your gas tank at least a quarter full. The pump is normally submerged in fuel, which cools and lubricates the mechanism. When the fuel level is low, the pump has to work harder to extract fuel from the bottom of the tank, and it is not cooled by the surrounding fuel. This can lead to unnecessary pressure on the fuel pump, causing it to fail prematurely.
Additionally, some high-pressure fuel pumps used for diesel or direct injection can be very loud, and it is normal for them to make a high-pitched noise. However, if your pump starts to make a noise that it didn't make before, it could be an indication that it is failing and will need to be replaced soon.
