What You'll Learn
Before replacing, check other components of the fuel system to verify the pump is bad
If you think your 2006 VW Beetle needs a new fuel pump, it is recommended that you check other components of the fuel system to verify that the pump is bad. A bad fuel pump will not push the fuel needed to the engine as it should, resulting in hesitation when accelerating or your Beetle may not start at all. However, these issues may not always be fuel pump problems. You may have a clogged fuel line or fuel filter. For newer VW Beetles, the fuel filter is an integrated part of the pump, so you will need a new pump.
To access the fuel tank and pump, look under the back seat. Before replacing the fuel pump, Delphi recommends cleaning the fuel tank to reduce the risk of contaminating the replacement pump. Fuel tank contamination is the leading cause of premature fuel pump failure. Use a fuel tank cleaning kit FFC01.
The fuel pump delivers liquid fuel from the fuel tank to the vehicle's injection system, where it is mixed with air for burning within the cylinders. The pump pressurizes the gas system to transfer gas out of the fuel tank and into the engine.
When replacing the fuel pump, use extreme caution as gasoline is likely to spill from the fuel lines. Never allow anyone to smoke or have an open flame when you're replacing the fuel pump.

Clean the fuel tank before installing a new pump to prevent contamination
Fuel tank contamination is the leading cause of premature fuel pump failure. To prevent contamination, it is recommended to clean the fuel tank before installing a new pump. This will ensure that your new pump is not damaged by debris, dirt, and contaminants that may have accumulated at the bottom of the tank.
Before cleaning, make sure to relieve fuel pressure to avoid the risk of fire and injury. Always work in a well-ventilated area, and keep a fire extinguisher nearby. It is also important to never smoke or work near an open flame or anything that could cause a spark, such as pilot lights and incandescent light bulbs. Wear safety glasses, and gloves are recommended. Keep clean-up materials on hand and clean up any spills immediately.
First, remove the fuel lines and siphon the fuel from the tank. Make sure the tank is completely dry, which may take up to 30 minutes. Clean the exterior of the tank, removing any rust and debris. Once the tank is clean and dry, you can install the new pump using the reverse procedure of removing the old pump.
By taking the time to clean your fuel tank before installing a new pump, you can save yourself time, hassle, and money in the long run. A clean fuel tank can also improve engine performance and fuel efficiency.

Remove fuel lines, then twist the pump out
To remove the fuel lines, you will first need to locate the fuel pump. For newer VW Beetles, this can be found under the back seat. Once you can see the top of the fuel pump, you can begin to remove the fuel lines.
This step requires extreme caution as gasoline is likely to spill from the fuel lines. Ensure that no one is smoking or has an open flame nearby when you are replacing the fuel pump.
After removing the fuel lines, you can twist the pump out, being careful not to get the fuel sending unit caught on the inside of the tank. Once the pump is out, you can attach any reusable brackets and pick-up screens to the new pump before installing it.

Reattach reusable parts to the new pump, then install
Once the old fuel pump is out, you can start reattaching the reusable parts to the new pump. Reusable parts include any brackets and pick-up screens. If your fuel system uses an in-line external filter, this is also a good time to replace it.
Now, you can install the new fuel pump. To do this, simply reverse the procedure that you used to remove the old pump. Ensure that all hoses and electrical connections are re-established.
Next, add fuel to the tank and run the engine to test for leaks. It is usually safe to drive, but the pump may lead to an overheated engine and catalytic converter. If the fuel pump problem involves leaks of gasoline or vapors, it is unsafe to continue driving, and the car should be checked by a qualified mechanic.
After installation, it is recommended to keep the gas tank at least a quarter full to maximize the life of the new fuel pump.

Refill the tank and test for leaks
Once you've installed the new fuel pump, refill the tank with fuel and run the engine to test for leaks. It's usually still safe to drive, but a leaking fuel pump can lead to an overheated engine and catalytic converter. If the pump is leaking gasoline or vapors, it is unsafe to continue driving, and you should immediately get it checked by a qualified mechanic.
Before replacing the fuel pump, the mechanic will power it directly to confirm that the issue is a failed pump, rather than a faulty power supply. When the fuel pump is replaced, a new fuel filter should also be installed.
If you're removing the fuel pump through an access panel, you won't need to drain the fuel tank. However, if there is no access panel, you must first drain the fuel from the tank and then lower the tank from the vehicle to access the pump.
To avoid spillage, exercise extreme caution when removing and installing the fuel lines. Never allow anyone to smoke or have an open flame when you're replacing the fuel pump.

Frequently asked questions
You can search for parts on Bosch's website or Amazon.com. You can also search using your VIN # or check the part # on top of the fuel pump.
A bad fuel pump will not push the fuel needed to the engine as it should. This results in hesitation when accelerating, or your Beetle may not start at all. You may also hear a whirring or humming noise coming from the fuel tank area.
First, check other components of the fuel system to be certain that the pump is bad. Next, check if there is an access panel above the tank in the passenger compartment. If there is, remove the pump through the access panel. If there isn't, drain the fuel from the tank and then lower the fuel tank from the vehicle to gain access to the pump. Once you can see the top of the fuel pump, pull off the fuel lines, being cautious as gasoline will likely spill. Twist the pump out, being careful to not get the fuel sending unit hung up on the inside of the tank. Install the new pump using the reverse of the procedure that you used to pull out the old tank.
