A failing fuel pump can lead to major engine performance issues as it fails to send the right amount of fuel at the right pressure to the engine. According to Automotive Repair Experts, a failing fuel pump is responsible for 10% to 20% loss of fuel efficiency due to too little or erratic fuel reaching the engine. The failure of a fuel pump to retain adequate fuel pressure may result in stalling, poor acceleration, or difficulty starting in the engine. In fact, some engines can use more fuel, as the engine compensates for the flying fuel economy.
As an example, John’s Auto Service, one of the top automotive repair workshops, said most of their clients saw a 15% decrease in fuel economy caused by defective fuel pumps. The shop explained that as the fuel pump started to defect, it would require the engine to work overtime to maintain combustion, which resulted in significantly decreased miles per gallon (MPG). The pump can barrel downed as well providing it a tough time to deliver a consistent flow and when this happens, the engine will misfire.
According to a study conducted by CarCareOrg, cars with fuel pumps running under optimum pressure tend to burn more fuel owing to less atomization of the fuel. If fuel is not being atomized properly, it will not burn efficiently, and will decrease the overall power and efficiency of the engine. It can cause higher emissions and more fuel consumption. In fact, low pressure fuel pumps can add as much as 25% to fuel consumption, which, if you drive an older vehicle with a less than new pump, equates to a lot of extra fuel.
In addition, Fuel Pump problems are frequently associated with dirty fuel filters or contaminants within pump systems. AutoTech Labs found that a clogged fuel filter can lead to a 10% drop in fuel efficiency, since less fuel is reaching the engine than needed to run at an optimal level. In these scenarios, the fuel pump has to work harder to send the fuel through the plant, taking up more power and lowering the complete gasoline economic system.
As Henry Ford said, “Coming together is a beginning; keeping together is progress; working together is success. Likewise, when all aspects of the fuel system are in sync with each other, the engine runs clean and fuel economy is optimized. But any glitch in this delivery, like a failing fuel pump, can result in suboptimal engine performance and high fuel expense.
