My Ride: 2001 330xi
M3 Fuel Tank Baffle

To those of you that replied to my thread of my 330xi starving for fuel on the race track during severe right hand corners at 3/8 tank, I wish to extend my gratitude for your responses. Some were pro for the baffle, & some were not so positive. I guess it depends on the car. For my car the M3 baffle worked perfectly. I ran the fuel level to about 1/8 tank & never had any starvation issues. The little tricks I've lerned on this forum are invaluable. Thanks again to all. Chas

Did you have to modify the baffle or is it a direct drop in?

No Al. It is a direct drop in. Should take 1/2 hr or less. Unless you have the rear seat clips bust your ball$ like mine did. Chas.

I can attest to the fuel starvation issue in my 330xi being solved at the track. It worked on my car. Ran it down to 1/8th of a tank & had 0 fuel starvation. It's definitly inexpensive enough & takes only about 1/2 hr to install. Hell, it surely can't hurt. Chas

You can order it from Tischer...I plan to do this and an M3 fuel pump at the same time.

is the m3 pump a higher flowing pump? any benefits to running it?


i'm definitely interested in this baffle though. we've been hitting fuel cut in my car during autox'es... hard right hand turns with less than half a tank of gas...

if anyone knows the part number let me know. i am having a hard time finding it on the etk sites

Any disadvantages to doing this? I haven't tracked my car yet, but I'd like to eventually. I also do drive some pretty intense roads over here occasionally (they're used for hill climbs at some points throughout the year)

Yes, the M3 pump flows more than the standard 3 series pump. In theory, there should be no advantage to running this with a stock motor. Start with the baffle, if you continue to have problems let us know and we'll re-evaluate your situation.

Just finished installing the baffle. It took a bit longer than I'd thought. Upon putting everything back together, tt was a b*tch to press down on the pump & lock ring assembly hard enough to get the lock ring to engage the thread. After I was done, my fingers are raw.
One tip: The baffle has the part number sticker on it when purchased. Peel as much off as possible. Whats left can easily be wipe off with a piece of paper towel soak with little bit of gasoline from the tank.
