Although seldom, change the fuel pump to avoid high engine repair or simply check time-to-time for better performance. Depending on driving conditions, fuel pumps can easily endure over 100,000 miles — and in most cases outlive the vehicle itself. But there are few elements that can affect their time on earth. The fuel pump itself can wear out quicker than anticipated if the quality of fuel is poor, filters become clogged or if you keep your tank on E more times than not.
Fuel Pump replacement can cost anywhere from $400 through to as high as close to and even over a thousand dollars for higher performance models, if the vehicle is expendive enough. Modern direct-injection engines utilizing high-pressure fuel pumps, for example, are likely to benefit from improved wear control as the cost of maintaining precise flow and pressure max levels. Fuel pumps, even those that are intended to last a lifetime of the vehicle (ex: Bosch), sometimes require periodical check-up in high mileage car or one with frequent heavy loads.
Stalling under load: If the engine stalls when you put your foot down, there may be a fuel pump issue. These alarms are indicative of the fact that now your fuel pump is not pumping in the right amount so as to keep up proper level combustion. Bosch, a leading brand in fuel system technology, says that reduced fuel pressure can cause misfires or power loss itself - and with high-performance engines requiring seamless delivery of their performance potential this is no doubt an important issue for the home tuner.
Without the proper maintenance, a Fuel Pump is nonexistent. For example, changing out the fuel filter on a regular basis prevents it from clogging up, and helps keep the gas flowing smoothly for your fuel pump to do its job. Having atleast quarter-fulled fuel tank also keeps the pump from overheating, because The gasoline helps cool the pump. Celebrity gearhead Jay Leno has said it best, that "a little preventative maintenance goes a long way," and this applies to parts in vehicles like fuel pumps.
As fuel pumps are not replaced as regularly, it is important to look after them and prevent possible impairment.
