Keep it filled For the sake of your fuel pump, do not run on empty. It is dangerous to drive with less than a quarter of gasoline in the tank If you run out of gasoline, do not turn on the car as it can cause overheating due to an anti-fuel fuel pump that relies on gasoline for refrigeration and primary lubrication. According to a 2019 study by AAA, vehicles running on low fuel are at least 20% more likely to have early fuel pump failure because the pump is thermally insulated when pumping gas. Leaving your tank at less than one-quarter full will cause the fuel pump temperature to rise, shortening its useful life.
Poor fuel quality can seriously reduce the life of a fuel pump Fuel contaminants like dirt or water can block the fuel filter and burden the pump but by pressing only once or twice when starting up you are not adequately providing the pump with enough atleast 20/30 seconds of on time to push out air from lines and charge them back. Changing your fuel filter every 30,000 to 40,000 miles (as many manufacturers suggest) can help prevent them. Fuel that is low in quality or contaminated, such as from unregulated fuel stations, will leave a gunk layer and add the pump to great stress Majorly it's due the deposits formed inside the Fuel system.
One more is how you drive. Rapid acceleration followed by stopping can put added strain on the fuel pump, especially in a high-performance engine where more fuel is needed during acceleration. By gently accelerating and driving the car smoothly, you will also put less stress on your vehicles fuel system, which can in turn increase the lifespan of your fuel pump.
Temprature can be a very serious issue. Upgrading your fuel pump to a high-flow version that is meant for better cooling will do wonders in high-performance vehicles. High-flow pumps help reduce heat buildup in the system resulting from more consistent fuel pressure throughout. For higher-temperature environments from driving, cleaning the fuel system and potentially letting more air get to the pump will also aid in cooling and extend life.
