I don't see anywhere in the maintenance schedule about when the fuel filter should be changed. My old 911 was to changed every 30,000 miles, and we know there's a lot of crud that probably gets sucked up from those underground tanks. Big job?

Relieve the pressure in the fuel line at the rail. - Disconnect the battery. - Raise the rear of the car, best done from the rear subframe. - IF you have an A4 space it tight and it helps if you remove the catback portion of the exhaust on the drivers side. - The filter is just up under the frame in front of the drivers side rear wheel - Remove the bolt holding the filter assembly to the frame. - This is where it gets messy... Remove the two quick connect fittings towards the rear of the filter, just squeeze the blueish colored tabs and pull the two lines from the rear side of the filter. DO NOT be right under this - a couple of cups of gas will come pouring out - trust me I got soaked... - Using the fuel-line disconnect tool, remove the line on the front side of the filter. This is tight, I was worried about snapping the line when I did mine but it will come out... Again, some gas will pour out and remember the filter itself is full. You MUST use the fuel-line disconnect tool here. The tool is made of metal or plastc and looks like a ring with a cutout and tail that slide between the connector on the line and the hard tab on the filter. Same tool is used if you ever remove the line from the fuel rail...it's the 5/16" one. - Clean up all of the fuel that went everywhere. - Put the new filter in place and bolt it down. - Reconnect the lines. - Reconnect the battery. - Turn the key in the ignition to pressurize the lines but do not start. Do this two or three times. - Check for leaks. - Replace the catback if you remove. - Lower the rear of the car. - Take it for a spin. Note: I made some small additions but the majority of this tip was posted by someone else but somehow it got deleted from the database. If I could remember the original author I would've made reference to him. Thanks

You can possibly have 2 different fuel filters, depending on what type of fuel system that you have.
If you have one stainless steel braided fuel line going to the engine, then you have the 10299146, which has a fuel pressure regulator built inside it. List is 54.28
If you have 2 stainless steel braided fuel lines, then 10287788 is your filter. This does NOT have a pressure regulator built in, and is $13.70 list.

Mid year 2003's and up with FFS Fuel System the fuel filter is in the tank and not necessary to change.

IT L Go, thanks for taking the time to offer instructions. My car has a build date of 01/03, so I guess it needs to be periodically changed. I'll figure every 30,000 miles or so like my last car.
