Replacing Fuel Pump In 2006 Mazda 6: Step-By-Step Guide

The fuel pump in a 2006 Mazda 6 is located under the rear seat. To replace it, you will need to remove the rear seat, disconnect the fuel pump relay, and then remove the old fuel pump. You will also need to release the pressure in the tank by removing the filler cap. When installing the new fuel pump, it is important to align the fuel pipe correctly and to tighten the pump securely. Some people have reported that accessing the fuel pump retaining ring can be difficult due to the design of the sheet metal in the car, and you may need to purchase or create a special tool to remove it.

Removing the rear seat

To remove the rear seat of a 2006 Mazda 6, you will need to first locate the spring-loaded tab that secures the rear seat cushion to the latch. Pull on this tab to release the cushion. Do this on both sides of the rear seat to completely free the cushion.

Once the cushion is released, you can pull out the seat belts. The shoulder belt latch will look different from the other latches, so be sure to use a flat-head screwdriver or a pocket knife to release it.

With the rear seat cushion removed, you will expose the access panel to the fuel pump. Remove the access panel by unscrewing the four Phillips-head screws that hold it in place.

Disconnecting the fuel pump

Step 1: Remove the Rear Seat Cushion

• Access the fuel pump by removing the rear seat cushion. Pull on the spring-loaded tab to release the cushion from the latch.
• Remove the seat belts and set the cushion aside.

Step 2: Access the Fuel Pump Module

With the cushion removed, you will see an access panel secured by four Phillips-head screws. Remove these screws and set the access panel aside.

Step 3: Disconnect the Fuel Lines and Electrical Connections

• Locate the fuel lines and electrical connections leading to the fuel pump.
• Carefully release the fuel lines by lifting a plastic clip with your finger and sliding it off.
• Disconnect any snap connectors attached to the fuel pump.

Step 4: Remove the Fuel Pump Assembly

• The fuel pump assembly is held in place by a collar, which is a large nut. You will need a special spanner wrench or a suitable alternative tool to remove it.
• Place a breaker bar or ratchet in the square hole in the middle of the collar if you need more torque.
• Once the collar is removed, carefully lift out the entire fuel pump assembly.

Note: Always exercise extreme caution when working with gasoline, as gasoline vapors and any sparks can lead to a fire or explosion. Ensure proper ventilation and take the necessary safety precautions.

Removing the fuel pump retaining ring

To remove the fuel pump retaining ring, you will need to purchase a special tool. The Mazda tool part number is #49F042001. This tool has four legs, three of which need to be lined up with the tabs on the retaining ring. You will need to adjust the tool so that the feet are not on the tabs but are instead tightly fitted into the grooves of the retaining ring.

Use a 1/2" drive breaker bar to turn the ring counter-clockwise while applying a lot of pressure. Removing the ring is challenging, but once it is loose, the rest of the process is easier. Gently lift out the pump assembly.

There is an alternative, cheaper tool available online, but it looks flimsy.

The fuel pump retaining ring can be challenging to remove, but it is possible with the correct tool and plenty of pressure.
