I just finished swappin out the fuel filter about an hour ago. I followed the instructions to a T and I had zero problems. I used a lift which made it extremely easier.

Thanks again

No. Nobody can answer this for you. Nine thousand posts in two years, and you can't read the thread? There are explicit references in this thread to starving the engine for fuel. Go take a look.

It's not really necessary. I'm a little more "shade tree" than most. When I change the fuel filter I do two things.

1) Assure the fuel pump is off. Key off or pull the battery depending on vehicle... but make DAMN sure it's off.

2) Work quickly. :lol: I usually don't lose THAT much fuel.

I don't recommend my methods to others. I've been wrenching on a lot of different cars for a long time now.

Feedback

I just did the fuel filter swap using this DIY. Here's some tips:

- You might as well remove the last two screws on the pan. They are easily accessible and easy to remove

- The feul spillage is really minimal. This is one reason I was so careful about taking off the tubes from filter. There isn't much, mainly the feul left in the filter.

- removing the tubes is easier than it seems. I was being a wuss because I expected to be splashed with fuel galore. Don't be a wuss. Just use some pliers and use the filter as a pivot.

This is a really easy thing to do. Thanks for the DIY.

I too did this following the DIY this past weekend except I did it on a 1999 328i. The first thing I noticed is my fuel filter is different than the 2001 330i pictured. The fuse was the same fuse, and everything else was the same except I only had one inlet hose and one outlet hose making things quite a bit easier.

A very easy job, took no time at all but did require a shower to get the gasoline smell out of my hands and out of my watch. Next time I do this I'll be sure to remove my wedding ring and wrist watch

Thanks to all on this thread! I just changed the fuel filter on my wife's 2001 325i, and the info in this thread really helped. I can't believe how incomplete the Bentley instructions are for this task.

One follow-up question: Have any of you had to replace the small section of vacuum tube that connects to the fuel filter and been able to get it from BMW? On RealOEM, it shows as discontinued. Of course mine tore at the bend as soon as I touched it, and I don't think my electrical tape repair will last forever.

Thanks, Cory

I think Autohausaz.com has the vacuum tube lines.

Car jack and stands will give you plenty of room. I did mine with Rhino ramps.

Not sure but it might be fuel vapours or trapped air.

It's normal. When you put in a new filter you generally get an increase in mileage, so as your going along the number increases because the computer is relearning/increasing its MPG.

Now, when it goes back down, you're probably driving harder or even just passing someone. When you disconnected the battery for the fuel pump, you dumped the computers memory, so it only has a couple of days of records of your MPG. When you drive for a month or two it stays much more stable, but with a limited sample size, it fluctuates more often.

Actually your car probably has done that before and you never noticed it.
If you were to fill up your car and then go out and just floor it and drive it hard for a few miles your car would say you have 200 miles to go or so.

If you then drive it slow and easy that number would increase because it's based on how many MPG you are getting. Since you are now getting more MPG as the car believes you have more miles theoritically left to drive and thus the number increases from 200 to 201, 202 etc.

If you reset something then it's relearning and that's probably the main reason, but it's perfectly fine.

Question, I changed mine yesterday (the 328 one, so with just one line on each side). I replaced the hoses with some generic fuel hose I had lying around, roughly the same size. All went well as far as I can tell, and no leaks after I was done, but I did notice a distinct petrol smell I got out of the car this morning after a long drive.

I'm not anywhere near my garage this week so I can't check it out now. However I don't see any visible leaks. Could it be that I haven't tightened the hose clamps enough? I'm always a bit gentle with hose clamps on rubber hoses as not to rip anything up; should I tighten them further?

Go to https://www.autohausaz.com

They are a reliable and reputable online parts dealer with free shipping on orders over $50. I saved a ton of money buying my parts from there this summer, including my fuel filter DIY.

Enter your car's information on the site and it will give you a list of the specific car parts that fits your specific car.

As a reference, I have a 330ci and the site showed that I would need a Mahle fuel filter.. and right now it's selling for $46. Cheaper than the $63 you quoted, plus you can get free shipping if you just order something else to bring it over $50.. maybe an extra oil filter for your next oil change.

I would double check those little metal clamps that are used to hold the hoses down to the filter. Maybe they are worn and are coming loose. Or maybe while changing the fuel filter you got some fuel on an exhaust pipe or something.. which may be causing the smell as the pipe burns the fuel residue when it gets hot.

Thanks man. I actually forgot about autohausz but it's a great site. Last year when I did my oil change, I ordered about $50 in filters (cabin, engine, oil). They only list 1 mahle filter, so I'm guessing just buy that and pop it in.

If there was something wrong with my fuel filter, I should have trouble all the time right, not just on cold starts?

Thanks for the tip. I actually had it checked out by a shop today, as it was definitely beginning to leak and I'm nowhere near my tools for the remainder of the week. Driving around in a car leaking fuel didn't seem like the safest idea at the time.

The clamps were fine initially, but apparently the hoses I used to replace the old ones with were not reinforced or braided like the original ones. Mind you, they were actually sold to me as fuel lines in a marine equipment store... but oh well.
Because the rubber wasn't reinforced, the fuel pressure bloated the hoses and almost slipped one of the clamps off. It was already leaking; would hate to have found out what would have happened if I waited even longer.

So a (no-brainer) tip to all of you, make sure you use properly strong rubber connecting hoses, preferably the original BMW part.
