What You'll Learn
The Bosch 044 fuel pump can be installed inside the tank
To install the Bosch 044 fuel pump inside the tank, you will need to purchase the necessary parts and follow a few key steps. Firstly, you will need to put the check valve and AN to 5/16th adapter on the end of the pump, removing the neck that is already there. You will then need to hack the stock fuel line feed to fit the pump, using cut-off pliers to cut the line and pliers to bend it open. After this, you can worm gear the pump to the stalk, bending the tray that the previous pump sat in out of the way.
It is important to note that you should use fuel injection clamps inside the tank when connecting the hose if you are not using AN fittings. Additionally, the Bosch 044 comes with a check valve that prevents fuel from flowing back into the tank when the car is off, but this may cause you to crank the car for longer when the engine is warm.
The Bosch 044 fuel pump is larger than some other pumps, so you may need to enlarge the hole at the base of the hanger when installing it inside the tank. You may also need to change up your hoses and fittings.

It can also be installed outside the tank
The Bosch 044 fuel pump can be installed outside the fuel tank. While some people believe that fuel pumps should be installed inside the tank, there is nothing wrong with mounting the Bosch 044 outside. This pump is quite large, so it may not fit inside the tank or in certain spaces within a vehicle.
If you are installing the Bosch 044 outside the tank, it is advisable to fit it as close to the tank as possible. This is to avoid any possibility of running the pump dry or suffering fuel supply issues. However, this should not be an issue in theory, as the 044 is a gravity-fed pump and cannot lift fuel itself.
To install the Bosch 044 outside the tank, you will need to split the standard fuel line from the tank and fit the pump inline. The inlet to the pump is a 12mm diameter push-on pipe fitting. The pump's outlet has a 12mm banjo fitting, but this can be changed to a straight screw-in fitting if needed. You will need to remove the valve on the outlet to do this, but it is not a big issue.
The biggest challenge when installing the Bosch 044 outside the tank is likely to be adapting the standard fuel line to the pump. The exact process for this will depend on your vehicle's specific setup. You may also need to install a fuel pressure regulator, but this is not always necessary.

This pump is capable of providing 300 LPH free flow and 200 LPH at 5 bar (or 72.5 psi) for up to 685 BHP. It has a minimum current of 12 volts and a minimum flow rate of 80 GPH (300 LPH) at the outlet.
The Bosch 044 fuel pump is commonly used in motorsports and high-performance vehicles. It is known for its high flow rate and ability to support high horsepower. This pump is often used as an upgrade from lower-performance fuel pumps, such as the Walbro 255hp, which can only support up to 390 horsepower.
The installation process for the Bosch 044 fuel pump can vary depending on the vehicle and the specific application. It is recommended that these inline fuel pumps be installed between the factory (or another aftermarket) in-tank fuel pump and the fuel rail. In some cases, custom fabrication may be required for the installation. Additionally, feeding these inline pumps with another pump in series can boost the output of the Bosch 044 fuel pump even higher.
The Bosch 044 fuel pump offers several advantages over other fuel pump designs. It operates with near-silent functionality and improved drivability. The turbine design of the pump also reduces wear and delivers a longer service life. The pump is also easy to install, with application-specific, illustrated step-by-step instructions included.

It is a high-pressure fuel pump
The Bosch 044 fuel pump is a high-pressure fuel pump designed to exceed specifications. It is widely used in motorsports and can be installed in-tank or externally.
The Bosch 044 is a popular choice for those seeking to upgrade their fuel pump and increase horsepower. It has a high flow rate and can be mounted inside or outside the fuel tank, depending on the configuration and space available.
When installed in-tank, the Bosch 044 sits underwater within the fuel it pumps. This setup helps keep the pump cool and submerged in the fuel cell. However, servicing the pump in this configuration can be challenging.
Alternatively, the Bosch 044 can be mounted externally, which some consider to be a "cheezier" option. This external configuration provides easier access for servicing but may require custom fabrication.
The Bosch 044 fuel pump has been replaced by the newer Bosch 200, which offers improved performance. The Bosch 200 has a higher flow rate, weighing about 15% less than its predecessor, and is safe for use with alcoholic fuels. Despite this, the Bosch 044 remains a popular choice for motorsport enthusiasts due to its performance and versatility in installation options.
