Yah thats the wrong one then. There should be 2 tubes sticking out from each end. Get Mahle or Kayser, both are OEs. Check rmeuropean and bmaparts. They have real good pricing and free shipping after a certain amount.

that's what I thought... dang. I need one by tomorrow... well not needed, but I'd like one. Having this weird p0461 code. However, the gauge reads fine, it just seems slow/underpower right now.

Too bad, but that code may be from the fuel pump. The fuel level senders are in the pump. There is a test in hidden OBD menu, search for the same and check the units.
There are a couple of threads here and bimmerforums about this code. Check them out.

Although replacing the fuel filter is always good, but it may not solve your issue if its sensor in the fuel pump.

I replaced the pump last night, went out and it threw it again. It is weird. If I baby it it won't throw the code, however if I stomp on it and it gets above 4k it'll throw it. Kinda sucks for climbing a hill or merging on the highway.

I did the hidden tests, and the left side read 1.7L in it with 3/4 fuel left.... which it should read all but 0 if not 0 itself. Haven't retried the test yet with the new pump.

Good DIY however a few things to note.

Pulling the fuse, does nothing. After I pulled the hose which was mounted closer to the engine, a HUGE load of gasoline squirted right into my head. Very high pressure.

Second, when you disconnect the hoses on the other end, fuel will non-stop come out of that end. I waited 5-10 mins and it never stopped, had to reinstall the new one to stop the flow. Lost of gas was wasted.

Third, you should buy 3 new hose clamps because those stocks one you can only lossen but can't retighten.

Fourth, sometimes putting the car from 2nd to 3rd in the ignition doesn't always help. I must of purged the system like 10 times, when started it ran like crap for 30 seconds before stabilising.

I replaced my filter last month and here are a couple tips that address some of the above.

1. after pulling the fuse, start the engine and let it run until it stalls. This will relieve the high pressure in the line.

2. the two hoses at the back of the fuel filter come from the two gas tanks. The reason fuel stops flowing from one hose but not the other is likely because you have less than 1/2 a tank of gas but not an empty tank. I would recommend performing this when the tank is nearly empty to reduce the flow.

hope this helps.

I replaced the fuel filter today. Had about one gallon in the tank so I thought this would be a good time to change the filter.

Removed the fuse and started the car. This didn't do much except to warm the car up.

Once car cooled down, removed the old filter. Didn't need any clamps and had minimal gas spill. Only about a 1/2 cup.

Reinstalled new filter. Reinstalled the fuse. Turn the key to #2 about five times with about a 5 second wait between each attempt, and then started up the car. Ran perfect.
Drove down to get a 1/2 of gas. All is good.
Over all took about 1 hour to complete this project.

Good DIY.

You can go to Orileys and ask for a fuel pressure regulator. It will be in a Borg Warner box part #24056. Open the box and you will find a Kayser fuel filter w/ built in regulator for around 55 to 60 bucks.

Just did this and thought I'd throw in my two cents... Never know when your experience might help someone...

-- Like most people, I find this to be one of those jobs that would be so much easier with a lift as opposed to just jack stands with the work about six inches in front of your face. Pretty awkward at times, but it still wasn't too bad.

-- Again like most, I couldn't get to or find the front shield fasteners, so I just bent it out of the way. No problem.

-- I have a 2000, so my car uses the simpler "1 in, 1 out" filter. I thought this would make the job a lot easier, but one little snag... I thought there was a short fuel hose on the front of the filter that connected to fuel line, just as on the back. I didn't realize that the front had a long hose that ran up beyond where I could see. Maybe they're all that way and I just missed something. I used the old hose anyway... And actually did the same thing on the rear as it seemed to be in okay shape.

-- Speaking of fuel hose, the guy at Advance tried to sell me regular cheap fuel hose even though I insisted I needed more robust fuel injection line. He insisted just as much this was the right stuff. So be aware out there of the counter people who don't know what they're doing. (I got the right stuff at Oreilly's and then ended up not even using it, as mentioned above.)

-- Hardest part of the job was getting the hose off the old filter. At first I thought it was completely welded on there and I'd have to cut it off, and because I didn't know what to do about the front, I was really stumped for a few minutes. But a little WD40, a few minute wait, and some pliers, and it came off fairly easily.

-- When I pulled the hose off, only a little bit of gas came out -- no crazy spraying. Pulled the front first, and some shot backwards, but not much. Just some a little ran out of the back.

-- My car has 180k miles on it, and the filter was original, production date 9/99(!)... I was pretty surprised that the gas that came out the front actually looked pretty clean. Of course when I turned it over, I got the black stuff you've seen in the vids.

-- Strange thing happened: One of my hose clamps wouldn't tighten down. It started to, but then I just turned and turned the screw and nothing happened. Because it was on the front hose where I couldn't see, I'm not sure what was going on. Had one more in my package and it worked fine. Weird.

-- When done, I went to position 2 on the ignition several times, for several seconds each, and the car started right back up, no problems.

-- Was anyone else half expecting to see a leak when they first checked with the car running? Maybe I'm just a pessimist. But everything seemed okay.

-- Like a lot of people have seen, there's now a drastic difference in my idle. I was at maybe 700 RPMs with some bouncing at first, especially when cold. Now I'm at a dead solid 950-1000 with no movement. I'd thought I had a small vacuum leak or needed to check my idle control valve, but maybe this is all it was. Cool. Can't wait to check that as well as my gas mileage going forward.

-- Thanks again to everyone who posts DIY stuff on here. It really helps noob mechanics like me who a few years ago couldn't do much of anything to his car beyond oil changes. No telling how much money this site has saved people over the years.

I'm glad people still use this, and I can't believe I posted it back in 2005.
I still have my car '01 330Ci with 222k miles on it and while the engine is ok, I either have large coolant leak at highway speed or possibly a gasket leak. I think it's time to get rid of her, and so with that, I moved on to my new ride.

I just purchased a 2011 LCI 335i M Sport with 22k miles, and I think I got a great deal. Once I drove a newer 335i, I was sold, and then it was just a matter of time before I decided which one I wanted. I'm sure I'll be doing some more DIYs in the future, but these cars don't seem to allow as much DIY mechanical ability as the older ones.

I guess time will tell, thanks for utilizing the DIYs. I'll surely do more, but the car still has the factory warranty until 50k or April '15, so until then!

Did this today. One thing I noticed reading through this thread is the people who didn't pull the fuse and starve the car seemed to have less fuel flow out. So I didn't pull the fuse or starve the car and sure enough I had a little over a cup come out and most of it was from the filter. Anyways all went easy for me except for pulling off the clamp from the front hose. The clamp was turned up and difficult to reach especially with the plate just bent down. It was a pain in the ass to get loose but once I did the rest went smooth. The old filter dumped out dark black fuel. I did this at my parents house and the average mpg's I would get driving to my house was between 15-17. After changing the filter, driving the same distance under same traffic conditions and same average speed I got a reading of 23.5 mpg. The old filter was original and my car is a 2002 touring with 105k on it. So far thats all I drove and wondering if that reading is correct. I'll know tomorgrow after driving some more. But the car is definitely driving a lot smoother with better throttle response. Thanks for the DIY.

Changed mine @ 50k and the gas coming out of it was black. Also it was the cause of cold start issues. The car would crank, die immediately, then run fine. Replacing the filter solved that issue.

Just changed it again @110k miles the other week. Gas coming out of it this time was clean and clear gasoline. No dirt or junk like there was before. I thought that was interesting.

It's a good idea to replace those hose clamps with more conventional ones, and also suggested to replace the rubber fuel line with new. That's all up to you though.

Oh yeah, protect your eyes. Gas will spray out like crazy when you first disconnect.

This seems to be correct. I didn't mess with starving the car, and didn't have much come out.

I need to play around, though, as I think I screwed up the shield or foam water block thingie. When driving at high speeds through heavy rain, I get really weird behavior (like a droning or something, and the engine behaves poorly).

Another fuel filter change-out survivor! Job was pretty straight forward and I had minimal gas spillage. But I still did this job out in the driveway versus the garage to prevent stinking up the house with gas fumes. Car has 77K miles on it, but the gas that came out of the input side of the filter was pretty much clean and clear.

PS: a 5mm nut driver is the ticket for removing and reinstalling the factory hose clamps.

Any site specific you guys suggest to buy this from? Want to make sure I am getting the OEM one and not an aftermarket one.

Wow. I may have to do this.

I get poor MPGs in the city like 15mpgs but great country/suburban mpgs (upper 20s/low 30s hwy)
