Assumingthat you have a vehicle with an internal combustion engine, a vital part of the system is a fuel pump, which delivers fuel to the engine. The fuel pump is responsible for moving fuel from the vehicle's fuel tank to the engine with sufficient pressure. From there, depending on your vehicle, different things can happen.
In the case of an older, carbureted vehicle, many of these pumps were mechanical and attached to the engine. They worked by pulling fuel from the tank with suction, and pressurizing it on its way to the carburetor.
An electric fuel is in a vast majority of the cars that are on the road today. This kind of pump turns on when you put your key in the ignition and turn to run/start. Usually, if functioning well, it sounds like a soft hum in the background of your car.
If there are any problems with your fuel pump, this becomes evident very quickly. Having a bad fuel pump can leave you stranded, so it is important to recognize the signs of a bad fuel pump and understand how much it costs to replace it.
One of the first things you might notice with a bad fuel pump is that your car sounds different when it is on. A well-functioning fuel pump generally gives off a soft humming noise when your vehicle starts up. If instead you hear a sharp whining sound from your fuel tank, then this is very likely a sign you need a new fuel pump. The first thing you should do if you hear this noise is ensure that you are not running below empty.
In modern vehicle fuel pumps, the pump assembly usually contains the fuel-level sending unit as well, so if your fuel gauge is not properly working, you can often trace it to a fuel pump assembly unit not functioning properly. In both cases, changing the fuel pump can rectify the issue.
Finally, you may not be able to get your car to start at all. Unfortunately, many pumps do not give any warning sign of their failure. Sometimes, a pump can die while the vehicle is on the road, and other times, the vehicle shuts off, the pump seizes, and never starts again.
The actual cost of replacing a fuel pump depends on several factors. The parts cost of a fuel pump is usually between $75 and $250, depending on the vehicle. If you are replacing the fuel pump yourself, beyond this it is just the cost of your time. Generally speaking, replacing a fuel pump is considered an intermediate-level task.
If you decide to go with a professional, you may be looking at a cost of between $400 and $600 to replace a bad fuel pump. You can search through our Preferred Shops in your area for a mechanic that can help with the fuel pump repair. Expect the actual replacement to take between 1 to 6 hours, depending on the expertise of the mechanic and the tools they happen to have on hand.
Whether you do the job yourself or have a professional do it, make sure that the fuel tank is properly cleaned of all contaminants, as years of fuel sediment can build up in the bottom of the fuel tank. Remember that AutoZone has all the parts and tools to tackle the job should you choose to do it on your own!

This pump works just like fueling at the station. Auto shut off makes it handy and safe. Connection to tank was quick and easy. I installed battery spring clamps for power and installed a lock to keep people honest.
This is the second Fill-Rite replacement I have bought, and I am a big fan. I got tired of rebuilding the Fill-Rite pumps that came on my 30-gallon Handy gas caddies. Bought my first GPI replacement about 3-4 years ago and it has been a strong performer. When the second Fill-Rite pump sprung an aggressive leak the replacement with a GPI was a no-brainer. Best part is - this one is even smoother and easier to turn than the last generation. Plus, it's made in the USA! Thanks GPI!
Some years ago I was taking an IPC and FR in a Piper Aztec. A few minutes into the climb, I shut off the aux pumps, one at a time. A few seconds later, one engine quit. I turned the pumps back on and the engine restarted. After leveling off and setting low cruise power, I tried turning off the pumps again, and found that the left engine was the problem. It would run fine with the aux pump on; not at all with it off.
We were told by users, maintenance shops and overhaul facilities that engine-driven and aux pumps routinely last to engine TBO. The manufacturers call for overhaul at engine TBO or at a calendar-year interval, most commonly 10 to 12 years.
Many electric boost pumps are mounted somewhere between the fuel tanks and firewall. For instance, on a Beech Baron the boost pumps are in the wings; in a Cessna 210, the boost pump is just aft of the firewall, under the floorboards.
You can buy a new pump, buy an overhauled pump or send the broken one out for overhaul. For engine-driven fuel pumps, the price differential between new, overhaul-exchange and overhaul is often low, sometimes only a few hundred dollars. Your choices for a new pump will be limited to the manufacturer of the pump installed by the manufacturer of the airplane and approved as original equipment or another pump manufacturer that has received a PMA or STC for its pump on your type airplane. That means a little homework on your part and price shopping.

The Kozmic mechanical fuel pump kit is ready to provide all the fuel you could ever ask for. Includes everything needed for installation other than the crank pulley (works with fluidamper or ati - You MUST ALREADY HAVE ONE OF THESE, if not we do sell them as well) and building the lines for plumbing. Sold optionally with no pump or regulator for the guys who may have them laying around already.
Our kit includes a new lightweight pump driven pulley that is drastically lighter than most kits using the off the shelf aeromotive steel hub pulley. We also opted to use the HTD tooth pattern belt for great engagement and strength at high rpm. Tested vigorously to 9500 rpm, this kit was on the outlaw winning car during 2019 Subaru Nationals.
The fuel pump transfers fuel from the gas tank of your car to the engine. Typically, electrically powered fuel transfer pumps are situated either inside or on top of the fuel tank. A fuel pump assembly may be made of steel and plastic. When removing the fuel pump, verify that the gasoline line doesn't have any pressure. Ensure there are no electrical outlets that are active close to the gas tank.
Lower-pressure manifold injection systems use electric fuel pumps mounted inside the fuel tank. The high-pressure direct injection system uses mechanical fuel pumps that are mounted on the engine. Diesel marine engines use high-pressure fuel pumps, Ports, and Helix. The positive displacement fuel pump with a diaphragm works by the diaphragm expanding and contracting to suction fuel. Similar to a positive displacement pump, a plunger-type fuel pump draws and distributes fuel through the reciprocating action of the plunger.
You will know that you need a fuel pump replacement when your fuel pump or injection pump is making a loud noise. You may also face difficulty starting your vehicle. Your car's engine will sputter and potentially stall if the fuel pump, which can be a petrol or diesel pump, is unable to pump out a steady stream of fuel at higher speeds. If your vehicle needs more fuel than normal, that also means that you require a fuel pump replacement. Besides, when determining the cause of problems with a fuel transfer pump, the fuel filter should be checked and replaced if necessary.
