Remove the rear seat cushion
To remove the rear seat cushion of a 2005 Mazda 6, follow these steps:
First, locate the two plastic clips on the front of the cushion where it meets the carpet. Run your hand along the front edge of the cushion until you feel the clips, then push them left or right to unlock the seat. This will allow you to lift the cushion up and access the fuel filter.
Alternatively, you can try removing the rear seat by lowering it and then folding it up towards the roof, as some Mazda models have latches that require this action to release the seat.
If the above steps do not work, there may be bolts holding the cushion in place. To access these bolts, you will need to remove the carpet in the trunk or lift the carpet from the back of the rear seats. There should be two bolts that you can unscrew to release the cushion.
In some Mazda models, there are white nylon clips with a black switch on the sides of the back seat that, when released, allow you to push the sides of the seat forward. To access these clips, you will need to remove the lining from the sides of the trunk and the black trim piece along the bottom inside lip of the trunk.
Once you have successfully removed the rear seat cushion, you will be able to access the fuel filter for replacement. Remember to refer to a service manual or seek professional assistance if you are unsure about any of the steps or procedures.

Mazda 6 has two fuel purification filters
The 2005 Mazda 6 has two fuel purification filters. The first is a small disc on the pickup of the fuel pump, and the second is an inline filter contained within the basket assembly. This design was first introduced with the Contour and has been continued with the Mazda 6. This is why changing the fuel filter is expensive, as you have to pay for the fuel pump assembly, not just the filter.
The fuel filter is located underneath the rear seats, and you can access it from inside the car. To replace the filter, you will need to remove the rear seat. Once the seat is removed, you will see a black plate with an electrical cable going into it. There are special tools required to remove the old filter and install a new one, with the grommet being the most important piece.
To access the fuel pump, you will need to lift up the rear seat squab, where you will see a cover. Under this cover is the top of the pump. You can use a hammer and chisel to turn the bezel around the top of the pump to remove it, or you can buy fuel pump removal tools that are available online. Once the pump is out, you will see the filter, which looks like a mesh bag at the bottom of the pump.
It is important to note that modern cars do not have replaceable fuel filters. They still have filters, but they are part of the fuel pump and not serviceable, meaning that you have to replace the entire fuel pump when the filter needs to be changed.
