Rubber gloves will be disolved by the gasoline...

oh and a tip for removing the hoses... get small needle nose pliers that dont have a rough gripping texture; put them open under the hose between the filterbody and hose, and then using the filterbody as a wedge push up the hose. This method popped the hoses off nice and easy with no damage for me.

Now I see why BMW doesn't replace the fuel filter at every Inspection II, because Mechanic says the official service life is 100,000 miles.

My experience was that at 85,000 miles, my 325i gas milleage suddenly went from 23mpg to 21mpg, so I replaced the fuel filter, and my mpg went back to 23+mpg. I suppose the regulator in the fuel filter has some seals that get soft and wear out.

Just cut the BMW filter open and look at the filter media, and compare it to a GM fuel filter, which also has a service life of 100,000 miles, as per GM. The BMW gas filtration-media component is about 5 times larger than the GM media, and I conclude that the BMW filter is much better than it needs to be, but the regulator portion has a slightly more limited service life.

Every expert ive talked to recommends a fuel filter change every 2 years. Even every year wont hurt. BMW says it will last up to 100k miles. They also state their transmission fluid is "lifetime." this is all BS. Even though the parts are more advanced today, they still wear down and decline in performance after a certain point. Thats why it never hurts to change the filter. and for $20 and half an hour or so, how can you go wrong? You also extend the life of your fuel pump and fuel system this way

I'd swear there was a schrader valve in the engine bay to relieve pressure in the fuel line... maybe I'm thinking of my old car, but I'll check next time I'm home. It makes things a lot easier.

Just changed it over the weekend. It was kind of different to get the tubes out of the fuel filter in the tight space. But it was well worth it for $40 and wasted some gas while changing. It seems like it fixed the RPM dead spot problem as well. At least now the car feels much better.

surprised

I'm surprised BMW uses simple hoses with clamps instead of some sort of quick connect mechanism. (which would make you run tot he store to get soem sort of special tool no doubt)
This part is pressurized so be sure to tighten the clamps enough.

Get a trim pulling tool

This would have been impossible without a trim pulling tool that I had lying around. It is essentially a mini pry bar; a small screwdriver sized tool with a fork at the end. I was able to pry the hoses off very easily with this after struggling with a screwdriver for 20 minutes.

even though i pulled the fuse, and let it die, then cranked it a few times, it still spayed fuel EVERYWHERE!! I would suggest trying to start the car a number of times with the fuse pulled... just my 2 cents.

My Ride: 02 330CI 3 Pedals
Fuel Filter

I just performed this over the weekend. It wasn't too difficult but I ran into a few unexpected things.

1) I would get 6 new clamps from the dealer before performing this. I have a 02 330CI and my clamps were not bolt shaped they were rounded and could only be removed by a screwdriver and needed pliers to tighten. I bought 4 new clamps and they can be removed/tightened using a 5mm socket.

2) after pulling fuse #54 my car kept starting and would not die, I proceeded anyway.

3) taking the hoses off is not fun, the pictures in the DIY show nice clean lines etc. Living in the northeast = havoc for your undercarraige. The lines meeting the hoses were full of gunk. I took an awl and cleaned where the house met the fuel lines to "break the seal" I removed the hoses from the lines first not the filter. then removed the hoses from the filter when it was off the car.

4) gas kept pouring out of one line from the tank in a pencil thick stream. I expected it to stop but it did not. Anyone else have this problem? So this led to my next issue.

5) I rushed to get the filter back on because the gas kept coming. well not only does it have a front and back, which was obviously correct, it also must be positioned properly on the lines. There is an arrow on both sides of the filter so it looked like It was right. Well my car wouldn't start, I checked the pics and realized I put the filter on upside down.

I then quit for the night and proceeded to kill two 64 ounce growlers from the local brewery to forget my stupidity and my anxiousness about breaking my car.

the next morning I inverted and fuel filter in 15 minutes and it started up first try.

I changed all of my fluids and filters this weekend for inspection II and I don't know if it's placebo but it revs faster and pulls harder.

Thanks to whoever wrote up this DIY in the first place. I've been dreading this for months but Never would have tried it without the pics.

This is one of the best diys ever. I just did this and had absolutely no problems.

Instead of bending the protective cover i just took out the extra bolts. Theyre the same size as the screws (2 of them)

I, too, followed this DIY (last year) --- and the only problem I ran into was that the bolts on the steel cover snapped ... I had to extract them out.

This is definitely the DIY guide to follow for changing your fuel filter!

If you have the older fuel filter WITHOUT the pressure regulator, it's even easier. I'dd add this to the DIY:
  • Leave the clamps attached to the fuel filter. Unscrew the ones on the outside edge of the hose.
  • Pry the hose off SLOWLY! Create a bit of gap to release the pressure (get ready for some gas spraying - not fun).
  • Take off fuel filter with both hoses still attached.
  • Measure, cut, and attach the new hoses to the new filter.
  • Slide the clamps in (2 per side).
  • Attach the fuel filter and hose back on the fuel lines with some twisting and turning.

Tips:
  • Get 4 clamps and 1-2 feet of new hose.
  • Tighten all the clamps at the end, because you want the bolt head facing down for tightening.
  • Gasoline burns the skin and face. I learned the hard way.
