# How long does a fuel pump last?

- **Typical life:** 100,000+ miles
- **Biggest factor:** Fuel quality and contamination
- **Replacement cost:** $450-$1,300

## Quick answer

Many electric fuel pumps last 100,000 miles or more, and some last the life of the vehicle. Contaminated fuel, a clogged fuel filter and electrical problems can make one fail sooner. There is no set replacement interval, so pumps are replaced when they fail or test weak. Check your owner's manual for any fuel filter schedule.

## What it does and why it wears out

The fuel pump moves gasoline from the tank to the engine at the pressure the injectors need. On most modern cars, an electric pump sits inside the fuel tank as part of a module that also holds the fuel level sender and a strainer. Many direct-injection engines add a second, high-pressure pump on the engine, driven by the camshaft, that raises fuel pressure much higher before it reaches the injectors.

An in-tank electric pump wears through its motor brushes, bearings and electrical connections, and it works harder when the strainer or fuel filter is clogged. Fuel flowing around the pump also helps keep it cool. Dirt, rust or water in the tank can wear the pump and clog the strainer. Corroded connectors, a weak relay and low voltage make the motor draw more current and run hotter. A failing pump often causes power loss under load before it stops completely.

## How long it lasts, by conditions

| Conditions | Typical life |
| --- | --- |
| In-tank electric pump, normal use | Often 100,000+ miles |
| Often driven on a near-empty tank | Can fail sooner |
| Contaminated fuel or clogged filter | Can fail sooner |
| High-pressure pump (direct injection) | Varies, check manual |
| Model with a pump recall | Check your VIN for a free fix |

## What shortens or lengthens it?

- **Fuel quality and contamination.** Dirt, rust and water in the tank wear the pump and clog its strainer. Buying fuel from busy stations and keeping the fuel cap sealed helps keep debris and moisture out of the tank.
- **Clogged fuel filter or strainer.** A clogged filter or in-tank strainer makes the pump work harder to push fuel, which raises its temperature and current draw. Some cars have a serviceable filter on a schedule, while others have one built into the pump module.
- **Running low on fuel.** The fuel around an in-tank pump helps keep it cool and lubricated. Regularly driving on a nearly empty tank can make the pump run hotter and pick up sediment from the bottom of the tank.
- **Electrical condition.** Corroded connectors, a failing relay, worn wiring or low system voltage make the pump motor strain. Burnt or melted connector pins at the pump are a common find when a pump fails early.
- **Pump design and vehicle.** Some vehicles have known pump problems or recalls, and high-pressure pumps on direct-injection engines can wear in their own ways. Checking your VIN for recalls can reveal a free replacement.

## Signs it is wearing out

- The engine cranks but takes longer to start, or will not start.
- The engine sputters, surges or loses power at highway speed or going uphill.
- The car stalls, especially when hot, then restarts after it cools.
- A loud whine or hum from the fuel tank area.
- No faint buzz from the rear of the car for a second or two when you turn the key on.
- Codes such as P0087 for low fuel pressure, or lean codes such as P0171.

## How to check it yourself

1. Turn the key to on without starting and listen near the fuel tank for a short buzz as the pump primes; silence can point to the pump, relay or fuse.
2. Check the fuel pump fuse and relay in the fuse box using the diagram in your owner's manual.
3. Have any codes read with an OBD-II scan tool; low fuel pressure and lean codes point toward fuel delivery.
4. Note whether power loss happens mainly under heavy load, such as climbing hills or merging, which fits a weak pump or clogged filter.
5. Ask a shop to measure fuel pressure and volume with a gauge, which is the clearest test of pump health.

## How to make it last longer

- Try to refill before the tank drops below about a quarter.
- Replace the fuel filter on the schedule in your owner's manual if your car has a serviceable one.
- Buy fuel from busy stations and keep the fuel cap tight.
- Keep the battery and charging system healthy, since low voltage strains the pump motor.
- Check your VIN for open fuel pump recalls.
- Have hard starting or power loss checked early, before the pump strands you.

## What does it cost?

## Frequently asked questions

### How long does a fuel pump last?

Many electric fuel pumps last 100,000 miles or more, and some last the life of the car. Contaminated fuel, a clogged filter, electrical problems and frequently running the tank nearly empty can make one fail sooner. There is no fixed replacement interval, so pumps are usually replaced when they fail or test weak.

### What are the signs of a bad fuel pump?

Common signs are hard starting, sputtering or power loss at highway speed or uphill, stalling when hot and a loud whine from the tank. A car that cranks but will not start can also have a failed pump. A fuel pressure test at a shop confirms it before parts are replaced.

### Does running on empty damage the fuel pump?

It can shorten its life. The fuel around an in-tank pump helps cool and lubricate it, and a very low tank can let the pump run hotter and pick up sediment. Running on empty now and then is unlikely to ruin a pump, but making a habit of it adds wear.

### How much does it cost to replace a fuel pump?

Fuel pump replacement usually costs about $450 to $1,300 at an independent shop, and more on some trucks and luxury cars. Most of the cost is the pump module and the labor to drop the tank or reach it through an access panel. High-pressure pumps on direct-injection engines are priced separately.

### Can I drive with a failing fuel pump?

It is risky. A weak pump can cause the engine to lose power or stall without warning, including in traffic or on the highway. If you notice sputtering, surging or hard starts, have it checked soon and avoid long trips. A car that stalls repeatedly should not be driven.

### Can a fuel pump fail suddenly?

Yes, a fuel pump can stop with little warning, often because the motor or its electrical connection fails. Many pumps give clues first, such as hard starts, whining or power loss under load. Checking the fuse and relay is a quick first step if the car suddenly will not start.

### Should I replace the fuel filter with the fuel pump?

Yes, if your car has a separate filter, because a clogged filter makes a new pump work harder. On many newer cars the filter is part of the pump module or is designed to last the life of the vehicle. Your owner's manual or the shop can tell you which your car has.

### Can I replace a fuel pump myself?

Some owners can, if the car has an access panel under the rear seat or trunk floor. Others require lowering the fuel tank, which is heavy and involves gasoline vapor and fire risk. Relieve fuel pressure first, work in a ventilated area and follow a service manual for your vehicle.

### What is the difference between a fuel pump and a high-pressure fuel pump?

The regular fuel pump sits in the tank and sends fuel to the engine at low pressure. Many direct-injection engines also have a high-pressure pump on the engine, driven by the camshaft, that raises pressure for the injectors. Either one can fail, so a shop tests both sides of the system.

### Can a bad fuel pump cause a check engine light?

Yes. A weak pump can set codes for low fuel pressure, such as P0087, or lean running, such as P0171 or P0174. Some cars also have codes for the pump control circuit. A lean code does not always mean the pump has failed, since vacuum leaks and sensors can cause it too.
