Changing the fuel filter is very straight forward. It is extremely easy. Follow the numerous DIY on this board regarding changing the OEM fuel filter.

Here are some tips that you might find useful.

1) The fuel filter is located directly underneath the driver seat on the under carriage of the car.

2) There are two ends on the fuel filter. The IN put is toward the gas tank. The OUT put is toward the front of the car. There is an arrow painted on the fuel filter. Just make sure the arrow is pointing toward the front and you will be OKAY.

3) There is a shield protecting the fuel filter from getting all banged up. Use 8mm socket to remove the nuts.

4) After removing the shield, the fuel filter is secured by a bracket. Use a 10mm socket to remove it.

5) The hose are secure by a bunch of clamps. Use a "flat top" screw driver to loosen the clamps. To tighten the clamps use a 7/32 socket or a pair of plier. You CANNOT tigten the clamps with a flat top screw driver.

6) Remove the rubber hose by wedging a screw driver on the rubber hose while pulling and twisting the fuel filter.

7) Be prepare to have lots and lots of fuel leakage. Clean fuel immediately. FUel will evaporate faster when smear around rather than sitting in a puddle.


SAFETY TIPS

1) Change fuel filter only in well ventilated area. I was changing my fuel filter outside and yet I still feel sick.

2) Have a fire extinguisher ready in case. Would you rather take the time to buy or find a fire extinguisher than have your car destroy or blow up?

3) When removing the fuel line or when fuel are leaking out, make sure you priodically ground yourself from static electricity. Just touch all the metal/steal components underneath your car every two-three minutes or so.

I just changed my fuel filter last weekend. While simple, it's a pain with all the gas that pours out. Make sure that you have a pan to catch and spills. If you're really smart use a couple of golf tees to plug the lines while getting the new filter ready.

While I love working on cars this is one thing that sucks.

clamp the hoses

FYI,
I changed mine last year. I bought red plastic clamps at the auto parts store, they cost me like $3. I clamped both inlet and outlet hoses as close to the filter as possible and kept the filter horizontal while removing it. I didn't have any fuel spill out at all.. Took about 20 min..

cool diy. BTW would changing the fuel filter make pressing the gas pedal when accelerating more smooth? These days, when I press down on the gas pedal, I feel a considerable amount of vibration from the pedals.

I just replaced my fuel filter, and had some more tips.

I depressurized the fuel system by pulling fuse 54 and running and revving the car until it died. This resulted in very little fuel spillage, what was spilled was just what was in the old filter. As I emptied the old filter, all the gas had black stuff in it, along with small particulate matter, like sand. The hose clamps are a bit difficult to close when they are covered in fuel, but you must use a pair of pliers. After everything was buttoned up, I let the car sit with the key in position 2 for a few seconds to build up the fuel pressure, but I still had to crank it twice. My service engine soon light was on, and the engine was running very roughly and had a significant loss of power. After driving around for about five min., everything was fine. The light went out and the engine was running smoother than before. Also, it seemed as if the engine was a bit peppier than before as a result of the new filter. I have just over 65K miles, so anyone in that mileage might want to replace theirs as well.

I just did my fuel filter this afternoon - the tip to pull that fuse was great, thanks! Had very little fuel spillage. One tip on top of yours, turn the key to Position 2 several times until you hear all the air flushed out of the new filter - you'll avoid the check engine and hard starting. Mine started smooth as butter on the first try after I did that.

Good Idea replacing the fuel hoses. I think I need to get my fuel hose replace because my car is reporting a fuel leak. I recently replaced my fuel cap so I know that it must be the hose itself

After how many miles should this be done? And does anyone have P/Ns for the filter and lines?

TIA

go to www.realoem.com to search for the part number.

There are two version of the fuel filter. The new version of the fuel filter for the newer e46 comes with an intergrated fuel regulator.

As a protest to e46fanatics.com I am no longer providing FREE technical assistance and FREE installation on my DIY.

To those people that I assisted in the past, it was fun meeting and working with you. For everyone else, I am sorry. People on e46fanatics nowadays care more about the OFF TOPIC page then contributing or helping members out.

How much clearance do I need to change the fuel filter? Do you guys think rhino ramps (~+8inches) on the fronts be enough to do this?

Here's approximately what it looks like (my car is just slightly lower):

Yeah that should be enough. I did mine before I lowered the car and didnt even need to lift it. Heck if your driveway has a slight slope in it you can put the back wheels in the street and the front on the driveway making a perfect gap under the car to get to it.
