What else should I replace when replacing a fuel pump?

When you replace a fuel pump, you should also install a new fuel filter. (Here's how to change a fuel filter in four easy steps.) Check the fuel line running from the fuel tank to the pump, and replace it if it's cracked or leaking. If you replace the fuel line, you should also install a new hose.

What do I need to know before changing fuel pump?

The fuel pump should make an audible noise if it's working properly. Whack the fuel tank: Have an assistant crank the engine while you hit the fuel tank with a rubber mallet. If the vehicle starts during this procedure, it's a pretty clear sign the electric motor inside the pump is bad.

Should you replace the fuel filter when you replace the fuel pump?

On newer vehicles, the filter might be in the fuel tank as part of an integrated fuel pump assembly. It may one that only gets replaced if the fuel pump needs replacement. Another location is on the vehicle frame outside the tank.

Do you have to remove the fuel tank to replace the fuel pump?

In most, you must drop the fuel tank, and first drain most gas if needed. Some vehicles have an access panel in the body to get to the top of the tank to remove the assembly without dropping the tank.

What does upgrading your fuel pump do?

An upgraded fuel pump may move so much fuel, the factory regulator cannot bleed off the pressure fast enough. This leads to higher than desired fuel pressures which means the injectors are spraying more fuel than intended. The consequence is an overly rich air to fuel ratio and a poorly running engine.

How to Diagnose and Replace a Fuel Pump

What is a good aftermarket fuel pump?

For the best fuel pump, we recommend the TopScope Fuel Pump. This fuel pump is durable, reliable, and includes a fuel pressure regulator. For a budget-friendly fuel pump, the Yoneda Electric Fuel Pump 12V is an ideal substitute. The fuel pump is easy to use and works with a variety of vehicles.

How do I know what fuel pump to buy?

How many years does a fuel pump last?

Answer provided by. Fuel pumps are meant to last around 100,000 miles, but most people never have to replace their fuel pumps. They are typically built to last since they are positioned in a hard-to-access place within your fuel tank.

What makes fuel pump go bad?

The biggest reasons for a fuel pump to go bad are contamination, overheating, and wear. It's quite common for debris and dirt to make their way into a fuel tank, which can then get through the filter and into the fuel pump. These contaminants end up blocking the flow and puts an unwarranted load on the fuel pump.

How much does it cost to install a fuel pump?

The average cost for a fuel pump replacement is between $220 and $1,062, depending on vehicle and age. Labor costs are estimated between $124 and $260, while parts are priced between $95 and $854. Estimates do not include taxes and fees.

Is oil filter and fuel filter the same?

Both are different, we change oil filter every single time oil is changed. Fuel Filter will be changed once in 30,000km and interval varies slightly for every car.

Why won't my truck start after installing a new fuel pump?

First, it's possible that the pump or some of the hose attachments are installed backwards or that there is a blockage somewhere in the fuel lines; typically at the first fuel filter. Finally, it's possible that you have a ground issue somewhere near the fuel pump that's causing a reduction in power.

What happens if you don't replace fuel filter?

Unless totally blocked, rarely will a bad fuel filter keep your engine from starting. On a vehicle where a fuel filter has never been changed, the dirty filter can cause erratic fuel flow, resulting in longer than usual cranking before the engine starts. Check your owner's manual on filter replacement intervals.

Will a bad fuel pump work sometimes?

A weak fuel pump may still pump fuel, but the vehicle may experience difficulty starting from the lack of pressure. A weakened fuel pump can cause the vehicle to take more cranks to start than normal, and in more serious cases may even cause the vehicle to require multiple turns of the key before it will start.

What are three types of fuel injection systems?

Can a bad fuel pump work intermittently?

There's no such thing as an intermittent mechanical fuel pump failure. Any power loss, engine 'choke' problems, etc. are being caused by something else. In a fuel injected engine, electric fuel pumps can fail intermittently.

Can a bad fuel pump cause electrical problems?

When an engine is running badly, many people start by blaming the fuel pump. While that could be it, the root of the problem is far more likely to be electrical, so start by looking at those things.

What are the signs of a bad fuel pump relay?

What are common fuel system problems?

A malfunctioning fuel system can prevent an engine from starting but so can other problems such as lack of spark, a blocked air intake, or a broken timing belt and simply no fuel in the fuel tank. Be sure to rule out these possibilities before continuing to diagnose the fuel system.

Can a fuel pump fail suddenly?

Fuel pump failures tend to be sudden and unpredictable, with few symptoms to warn the motorist that trouble is brewing. And the higher the mileage on the vehicle, the greater the risk of a fuel pump failure.

What is the difference between a fuel pump and fuel pump assembly?

The fuel pump assembly in a vehicle is responsible for sending the required amount of fuel at the right pressure and time to the engine. The assembly consists of a few key parts such as the screen filter, fuel pump and fuel pressure regulator.

Are all fuel pump the same?

Fuel pumps have different flow rates at different voltages. As voltage increases so does the speed of the fuel pump which will increase the flow of a pump at any given pressure. Because of this it is good practice to see how a pump is rated at a given voltage. Most cars will produce about 13.5 volts when running.

Do fuel pumps come with fuel filter?

Today's newer cars typically include the fuel filter as part of the fuel pump assembly – and you'll need to replace it every 5 years or around 30-50k miles. I recommend you check your owner's manual for the specific service interval, as it does vary between makes.
