A fuel pump is one of those parts that are designed to last the lifetime of the vehicle, but because it is part of the very elaborate fuel system, and because it plays a crucial role in engine performance, service engineers need to ensure they are taking proper care. Among the most common is a dirty fuel filter, which can limit the flow of fuel and cause the pump to overwork, shortening its useful life. A clogged filter can decrease the pump efficiency by 20-30%, which will reduce its usable life. Although replacing the filter regularly, typically scheduled for 30k to 50k miles, can stave off these issues, the pump itself is normally quite difficult to access as it sits inside (or under) the fuel tank and requires removing said tank adding costs and complexity to maintain.
Swiss track the 5th Among the problems is constantly bad quality of fuel. Fuel with impurities such as dirt, water or debris can ruin the pump over time. Corrosion inside the pump is detrimental to its efficiency and eventually results in failure. According to a 2019 study from AAA, low-quality fuel leads to 3% of vehicle breakdowns, and the victim is often the fuel pump. Fuel system cleaner Fuel additives may help to clean the system, but you can't rely on them for proper maintenance.
This cars also have the electrical components of the fuel pump, which can get tricky. Because the pump uses electrical wiring and connectors to operate, having loose connections or old times wiring can cause intermittent or total pump failure. The problem requires electrical diagnosis, which can take time for an electrician to check the voltage and continuity of various components. According to junkyard parts database Row52, electrical problems are the cause of 25% of all fuel pump deaths on that site; that's a good reason to add it to your maintenance checklist.
The use and upkeep of the pump is produced even much more hard by exactly where the pump is situated. This is because the majority of new vehicles have the fuel pump mounted inside the fuel tank to keep it cooler and running at a more constant temperature, but that design means that replacing the pump requires removing part of or most of your exhaust. Labor to remove the tank and safely handle the fuel can compound replacement costs 40-50% more than other engine components.
Of equal importance is the fuel pump relay, which determines when the pump will activate. A defective relay could inhibit the pump from delivering enough pressure which would cause your vehicle to exhibit poor acceleration or stalling Hoses can get pinched. A faulty relay is often misdiagnosed as other engine problems, such as a bad fuel pressure regulator and some cases may require special tools to properly diagnose.
In the wise words of Elon Musk, "You have to be pretty driven to make it happen. It's not all fun," adding that "the road to success is taking risks that everyone says you shouldnt take on but also being fiscally responsible and maintaining efficiency." By inspecting and correcting these smaller fuel system problems, you can avoid larger catastrophic failures.
