Solving the Mystery of What Killed Your Fuel Pump
The primary job of a fuel pump is to deliver fuel from the tank to the engine. From there, fuel is distributed to injectors where it is sprayed into each engine cylinder combustion chamber. On older vehicles, the pump sends fuel to the carburetor.
Most fuel pumps should last well over 100,000 miles. If your car won’t start, dies under a heavy load, accelerates poorly, sputters, or begins to have decreased gas mileage, you may be running into fuel pump issues.
Even though your fuel pump is not included in regular maintenance, you can still take steps to increase its lifespan. The following are a list of fuel pump killers and what you can do to stop them before they send your pump to an early grave.
Fuel Pump Killer #1—Running on Empty
Some folks think that that the E on their fuel gauge stands for Efficient. These thrill-seekers are too busy to get fuel except when absolutely necessary. The only problem is that this strategy subjects your fuel pump to unneeded wear. For many cars, the pump is submerged in the fuel within the tank. Gas does double-duty here. As well as providing the energy to get your car down the road, it also cools and lubricates the pump. When your tank is below a quarter tank, the pump is exposed and has to work harder and hotter—so, fill ‘er up!
Fuel Pump Killer #2—A Dirty, Rotten Fuel Filter
The fuel filter stops accumulated sediment in the tank from getting into the pump. You don’t want a dirty, rotten fuel filter. It’s critical to replace it according to the manufacturer’s recommended timeline. Clogged filters can create unintended pressure within the fuel system, leading to a harder-working, shorter-living fuel pump.
Fuel Pump Killer #3—Contaminants
A likely pump killer is contamination in the fuel tank. Sometimes this comes from the fuel itself. Make sure to buy your gas at a reputable station to ensure you are giving your car clean fuel. Older vehicles can have sediment in the tank from years of rust and corrosion. In some cases, you may need to thoroughly clean or replace the tank.
It Lived a Long, Productive Life
Even if you treat your fuel system well, if you own your car long enough, the day comes when your fuel pump dies of old age. When it does, bring it in to EuroCar Service. We will replace the pump on your Audi, BMW, Fiat, Land Rover, Jaguar, Mercedes, MINI, Saab, Smart Car, Volkswagen, or Volvo with a quality replacement component that meets or exceeds your vehicle manufacturer’s specifications. The entire assembly should be replaced and your EuroCar service advisor will install a replacement pump that is compatible with your fuel type. For example, if you have a FlexFuel vehicle that can run on gasoline with up to 85% ethanol content, your fuel system components—including the fuel pump—must be able to withstand the corrosive effects of high alcohol content fuel.
