Great vid btw, I love the ones that are to the point. No loud music, or person that thinks they’re funny, making a vid twice as long and you can’t find the info you need. To each their own, but this is the type of vid I like and it’s very much appreciated!

BMW knows this is a problem, yet they still produce a shoddy plastic regulator cap that eventually cracks and leaks. I did this job on my 2008 335i 2 years ago and yesterday I smelled gas inside my 2010 335i and sure enough it is leaking too. If you have over 120K miles on the e90, you will be doing this job. Thanks BMW. The hardest part for me was the clearances for the tubes and having to fish the tubes from the right to left side and remember how it goes back together. Not too hard if you keep a note of how it should look. Also squeezing the regulator in the hole is only difficult because I was afraid I would bend something because you have to squeeze, push, twist until it goes through. For my 2010, I know I can do the job, but so much work. I'm going to clean the regulator cap, sand it a little and put a ton of JB weld on it and hopefully not have to replace it. Once I watched the video on how to do it, it brought back some nightmares of the first time I did the job. Worst case scenario it doesnt work and I have to do the job later.

thanks so much for this video. just did mine. clips were a bitch to get apart, I almost gave up at some points. thankfully nothing broke. I unplugged the negative on the battery after de-pressurizing the regulator just to avoid any freak accident spark ups. took me an afternoon but got it done. used flathead and hammer to get the caps off each side

I just replaced the pressure regulator due to leaking. But it won’t start. The fuel pump was working fine before so I don’t think it’s the pump

I'm confused, did you remove that fuel line twice?

Just two symptoms. Fuel gauge stuck at 3/4 all the time (it goes back to 0 when I turn off the car) and gas smell inside suddenly. No leak on top of the regulator or pump. It is a little bit wet, but it looks like dirt and it doesn't smell like fuel. When I'm driving it, it smells less. When I leave it overnight, than tomorrow smells bad. What could it be? If it is sending float unit, I mean, if the float is stuck or bad, it should not have anything to do with smell of gas, right.

So I have a 2011 bmw 328i xdrive and on cold start it takes about 3 seconds before it starts and after that is starts right up. It always has a long crank in the mornings. If I don’t smell any fuel inside the car does this mean it’s not the fuel regulator? I’m really thinking it’s the fuel regulator but again I don’t smell fuel. Car has 149000 miles

You ever hear a surging or a growling sound after you turn the heater or AC off? My 2007 e90 335i makes a intermittent growling sound at idle from somewhere under the hood (driver side) usually after I turn off the AC

Do you have to replace both or can you just replace the pressure regulator?

With my 2007 e90 328i sedan, I smell fuel on the (outside only) the driver's side around the rear seat after driving. No visible fuel pooling or dripping on the floor. I'm also currently getting fault code - 2C31 (oxygen sensor control -post catalyst fuel trim system too rich, Bank 1), and the previous scan indicated 2C6B that has not reappeared after clearing. I'm suspecting it's the fuel pressure regulator but have not yet checked under the seat. If that is the case, could it trigger those codes?

Bought my E90 at 180k so i might as well wait to get a new fuel pump also before i go about doing this.

Should the tank be able to move around 😂. I’m guessing somethings loose

If this kind of leak goes on for too long, will it start to leak down the side of the tank? I took my seat off and smelled gas from the regulator; however, underneath the car there is fuel all over the bottom of the tank.

So just by disconnecting the electrical on the fuel pump, and attempting to start or starting it and letting it run is sufficient enough to depressurize the fuel system? Thank in advance

All the work is juet replacing the seals? And that will fix the smell?

So what exactly was your problem?????

job done but my battery died when i tried to start, i had all doors open and had not drove for 3 days

overly engineered system all to keep all those guts in the tank itself. Thanks CA.
