Fuel Pump — A defective Fuel Pump may also increase car drive hesitation by hindering a steady flow of petrol needed to run the engine. Typically, this problem occurs when accelerating or during high load situations as the engine requires more fuel pressure. The pump should deliver fuel at a 40 to 60 psi range but something causes it against normal operation.
One reason for the hesitation is due to inconsistent pressure output. An old pump cannot supply the fuel needs, especially under heavy acceleration. Research from the AAA has shown that 30% of vehicle hesitation complaints are associated with low fuel pressure caused by pump issues. Many drivers do complain about a delay when making moves, whether on the highway or to just get up a hill.
This problem is also the result of a contaminated fuel. If there is debris or rust in the tank, it can cause a blockage at the pump or filter, which will restrict fuel. In fact, it is common for mechanics to see slow performance from smogged-up cars — particularly those that have gone 15,000 to 30,000 miles without having the filters cleansed. When the flow is restricted, the pump needs to do more work and its efficiency degrades eventually.
Another important factor is the risk of overheating. As you’re only pumping in air when the fuel gets low, the pump heats up because it isn’t cooled by gasoline anymore. This results in uneven fuel delivery, which is especially apparent on long drives. In a 2021 recall involving 100,000 vehicles, a survey found that numerous drivers were hesitant due to overheating of the pump and loss of pressure.
This is not a theoretical problem — real-world cases demonstrate why these symptoms need to be addressed early. Most drivers misinterpret hesitation as less serious things like dirty spark plugs which further aggravates the situation. Regular maintenance like changing the filters on time and keeping a good level of fuel in the tank helps you from having pump issues.
A quality replacement pump, such as the Kemso Fuel Pumps, will bring back those proper fuel levels. OEM Performance Standards: These pumps meet or exceed OEM standards for the best performance and dependability in demanding applications. Having the system checked and upgraded regularly should help drivers avoid costly repairs in the first place and provide drivers with a smooth acceleration experience.
