What is a common indicator of a failing fuel pump?

A common indicator of a failing fuel pump is decreased fuel efficiency. The fuel pump is responsible for delivering fuel from the tank to the engine at the proper pressure. When the fuel pump begins to fail, it may not supply fuel efficiently, leading the engine to work harder for the same amount of power. This inefficiency often results in increased fuel consumption, meaning the vehicle uses more fuel than normal to operate effectively. Consequently, drivers may notice that they need to fill up their gas tanks more frequently or that they are getting fewer miles per gallon than usual.

Other indicators of a failing fuel pump could include sluggish acceleration, engine misfires, or stalling, but decreased fuel efficiency is one of the most noticeable effects that drivers may experience on a regular basis.
