My 2006 Aurion ATX now has 225,675 kms on the odometer. It could be somewhat overdue for a fuel filter replacement. I do not know whether the fuel filter was replaced before 165,000 kms when I bought the vehicle. Ryco Z646 or equivalent is a direct fitment for the 40 Series Aurion. I have previously watched a number of YouTube videos. Removing the bottom cushion of the rear seat was relatively easy. Prying off the cover was also easy but that black adhesive is messy. I used 2 small screwdrivers, 1 to push on the retaining clip of the electrical connector and the other one to pry it up. As per the YouTube videos, I started the engine which only ran for a minute before dying and this reduced the system pressure. I then fully removed the yellow plastic retaining clip and the hose came off quite easily. I used a large round magnet [instead of a parts tray] to keep track of the small 8mm ring retaining bolts. It was quite easy to manouvre out the fuel filter and pump assembly. Hard part was disassembling the various components to get down to just the fuel filter body. Multiple small screwdrivers and/or pick tools will be needed to unclip various parts. Hardest challenge was removing the sender unit which I found out has 2 parts. Upper part can be removed by pushing upwards. Base component is removed by pushing downwards so that the underneath tabs move into a small rectangular area then it releases and can be pried loose. Fuel pump is removed by pushing downwards. An upper o-ring is what holds the pump in position. I tried to spray clean the fuel pump strainer sock but no noticeable difference. Fortunately, I had previous bought some on eBay which were a smaller size but did fit. This is the type of strainer sock with a straight hole for the retaining clip. https://www.aliexpress.com/item/32788433064.html Round metal item located at the bottom of the fuel filter body is also held in position with an o-ring. Just needs a bit of leverage to come loose. It would be nice to say that everything worked the first time. However, not the case. Big learning is to check that you have no parts left on your work area. I had forgotten to reclip a bottom retaining cover under the fuel pump and which also retains that abovementioned round metal item which I had to fish out of the fuel tank. Fortunately, everything is working and engine is able to idle and accelerate nicely. Something that I noticed the next day is that the engine is now idling lower by about 100 rpm. The fuel sender unit is working showing fuel level at the expected half level. Next test will be to refuel the car and check the indicated fuel level. Overall, this is a task which can be done in 2-3 hours. With a lot better preparation, you should be able to reduce that to 1-2 hours. I will post some pictures later and possibly some links to worthwhile YouTube videos.
