The cost of a new fuel pump depends heavily upon the make and model of your vehicle. Most fuel pumps cost less than $150. However, the cost to replace a fuel pump is usually much higher. Fuel pump replacement usually costs $600 to $1,200, although some high-end vehicles might cost you as much as $2,000. The reason for the high cost is the fact that your vehicle’s fuel tank will likely need to be drained and lowered to complete the job. It might take an experienced mechanic several hours to complete this job, and those labor costs will add up quickly.
