Additionally, a hissing or whining noise in the Fuel Pump can indicate that the pump is overworking due to restricted fuel flow caused by contamination. Contamination sometimes results in poor fuel combustion and can cause engine misfires or rough idling. Some of the symptoms may temporarily be relieved by the addition of fuel additives or detergents, but these certainly are not long-term solutions if the fuel contamination is severe.
In cases of suspected contamination, the fuel filter and fuel lines should be checked for blockage or visible debris. For instance, on a 2017 Chevrolet Silverado, a clogged fuel filter resulted in a huge loss of engine performance due to the collection of dirt in the fuel tank during a long road drive through areas with poor fueling stations. In these cases, cleaning or replacement of the Fuel Pump may be required to regain the vehicle's optimal performance.
How Do You Identify Fuel Pump Contamination Issues?
The first evidence of Fuel Pump contamination often comes through apparent performance issues like hesitation or stalling of the engine. For example, a loss of 10-15% fuel efficiency or failure of smooth acceleration can be the reasons for malfunctioning of the Fuel Pump due to contaminants. Dirt, rust, or water contaminants can block the inner structure of the pump and reduce its capacity to feed fuel efficiently to the injectors. Some owners of a 2020 Ford Mustang reported running the car with low-quality fuel that contained too much water, which contaminated the fuel system and resulted in poor acceleration.
One definite indication of contamination is a loss of fuel pressure. Fuel pumps are designed to run at a certain pressure-for most vehicles, it is within the range of 40-60 psi. A loss of pressure below specifications-say, a drop of 5-10 psi-would indicate that the pump is not able to supply sufficient fuel due to blockages or deposits. Other symptoms include sludge or debris in the fuel filter, which many times indicates contaminants that have entered the system. Indeed, one report by the Automotive Service Association showed that more than 30% of all fuel-related vehicle failures were traced to contaminants entering the fuel system, especially from poor quality fuel sources.
