To replace your car’s fuel pump, the things you will need are:

Fuel Pump

When you begin replacing your fuel pump, confirm that you are in a safe place and have a fire extinguisher near to you as well. After that, relieve the fuel pressure and mean while cut power to the fuel pump.

Usually, an electric fuel pump generates high fuel pressure to bring plenty of pressurized fuel in your electronic fuel injection system plenty of pressurized fuel. Because you turn the engine off, the pressure does not go away. You probably need to take appropriate steps to release the fuel pressure earlier than you can take out the fuel pump or any related components.

Once you are confident that there is no fuel pressure in the fuel lines or fuel pump, you can go on with the fuel pump removal. To start you should also cut off the negative terminal to your battery to keep away from any shorts

Unbolt the Fuel Pump: Under Car Setup

Now it is time to unbolt the fuel pump. You must know that there are two categories of electric fuel pump. One type mounts in the gas tank, the other one mounts beneath the car opposite the fuel tank. You may come across your fuel pump by sliding under the car (if you cannot fit, you can put the car securely on jack stands) and getting in front of the gas tank on one side of the car or else the other. For ease you may also go behind the fuel line from the tank to the fuel pump. The pump will normally be there in a black insulating cover. Now unbolt the pump and let it drop vaguely. You would be unable to take away it from the cover until everything is disconnected.

Unbolt the Fuel Pump: In-Tank Setup:

You have to remove the fuel pump from inside the car if it is mounted inside the fuel tank. The access point through which you may get to an in-tank fuel pump is either under your back seat otherwise it will be under carpet and its access panel in the trunk.

When you have came across the pump, then you will require cutting off everything earlier than you take away it from fuel tank. You will learn it in the following steps.

Disconnect the Fuel Lines:

When you see all the things clearly now disconnect the fuel lines. In case there is an in-tank pump, there will be one line on the peak of the pump that you have to disconnect. On the other hand, if you have two lines, a line in and a line out (which are called the low pressure and high pressure side of the pump) then remove these lines, make loose the hose clamp or fitting that are grasping the low pressure side in, after that release the fitting and take out the line. To keep away from gas leaks from the lines you have to wear something on your hands. It will protect you from numerous risks.

Disconnect the Fuel Pump Wiring

Finally you have to disconnect the wires that power the pump. You will find two wires one is positive and the other ground. To disconnect first differentiate among them.

The wires will be clinging by plugs, small bolts or screws. You can now remove the pump when all things are disconnected. It is obvious that installation is the reverse procedure of removal so move ahead to do it.
