2.Relieve the Fuel Pressure and Cut Power to the Fuel Pump

An electric fuel pump produces high fuel pressure to supply your electronic fuel injection system with plenty of pressurized fuel. The pressure doesn’t go away just because you turn the engine off. You’ll need to take steps to release the fuel pressure before you can remove the fuel pump or any associated parts.

Here are instructions on how to release your fuel pressure in one simple step. When you’re sure there is no fuel pressure in the fuel lines or fuel pump, you can proceed with the fuel pump removal.

3.Unbolt the Fuel Pump: Under Car Setup

There are two types of the electric fuel pump. One type mounts inside the gas tank, the other mounts underneath the car just in front of the fuel tank. If your fuel pump mounts underneath the car, it will be held in by a couple of bolts. You can locate your fuel pump by sliding underneath the car (if you can’t fit, you can place the car securely on jack stands) and looking just in front of the gas tank on one side of the car or the other.

You can also follow the fuel line from the tank to the fuel pump. The pump will often be in a black insulating sleeve. Unbolt it and let it drop down slightly. You won’t be able to remove it from the sleeve until everything is disconnected.

4.Unbolt the Fuel Pump

If you have the type of fuel pump that mounts inside the fuel tank, you’ll need to remove it from inside the car. The access point to an in-tank fuel pump is either underneath your back seat or if you’re lucky it’s under a carpet and an access panel in the trunk.
When you’ve located the pump, you’ll need to disconnect everything before you remove it from the tank.

5.Disconnect the Fuel Lines & Fuel Pump Wiring

Now that you can clearly see everything, you need to disconnect the fuel lines. If you have an in-tank pump, there will be one line on the top of the pump that needs to be disconnected. If you have an under car pump there will be both a line in and a line out. These are also called the low pressure and high-pressure side of the pump.
To remove the lines, loosen the hose clamp or fitting that are holding the low-pressure side in, then loosen the fitting and remove the line.

The last step in removing your fuel pump is disconnecting the wires that power the pump. There will be two wires, one is positive, the other ground. It’s a good idea to make a note of which is which. What seems obvious while you’re taking it off can be baffling when it’s time to put it all back. The wires will be held on by plugs, screws, or really small bolts.
