The average Chevy fuel pump lasts anywhere from 50,000 to 60,000 miles. However, there are a number of factors that can affect the lifespan of a fuel pump, including the type of vehicle you drive and how you drive it. If you frequently drive in stop-and-go traffic or regularly tow heavy loads, your fuel pump is likely to wear out sooner than someone who drives mainly on highways. Additionally, the quality of gas you put into your tank can also affect how long your fuel pump lasts – if you use lower-quality gas or don’t regularly maintain your vehicle, your fuel pump will likely need to be replaced sooner than someone who takes better care of their car. Ultimately, the best way to extend the life of your Chevy’s fuel pump is to take good care of your vehicle and keep up with regular maintenance.
