Fuel pumps do require periodic testing for proper operation, especially in old age or at high mileage. Most manufacturers recommend an inspection of the fuel pump around 100,000 miles, but performing tests much earlier is very advantageous if the vehicle starts showing signs of problems with its fuel system. Testing helps identify problems like low pressure or inconsistent fuel delivery that might lead to poor engine performance or even an engine failure.
A fuel pump works effectively in terms of sustaining pressures within the normal range between 30 to 80 psi, depending on set requirements specified by the engine manufacturer. When this pressure is below the setting, the engine might suffer from misfires, or it will not start easily. These drops in pressure may be noticed early through routine tests and may save expensive repairs later on. The basic fuel pump pressure test costs anywhere between $50 and $100, which is quite more reasonably priced compared to the full replacement of the pump, which can go as high as $800.
This is again quite important with those vehicles operating under extreme conditions of weather, such as extremely cold or very hot climate. The fuel system does undergo more stress compared to normal operating conditions and thus reduces the lifespan of the pump. For example, a report by the AAA in 2018 indicated that vehicles under extreme conditions are twice as likely to develop fuel pump failures compared to those used in moderate climates.
Of course, the worst fuel quality can account for blockages or even corrosion of the fuel pump. Usually in these cases, routine testing can prevent severe problems from happening. Drivers who most frequently use lower-grade or ethanol-blended fuels should do this more often due to the higher risk of contamination.
As the great entrepreneur Richard Branson once said, “Take care of your employees, and they will take care of your business.” The same principle goes for maintaining automobiles: taking good care of such a critical component as a fuel pump means that your car will serve longer and will not let you down in the form of some pricey breakdown.
