Same here, next pay check this will definitely be done

Hey Smolck, thanks for the clarification on the pump location!

I am thinking about replacing the fuel pump relay too, just to be sure.

For those of you with pump failures, does it usually fail on a start, or does it fail while driving?

On BOTH my E46s the failure went the exact same. Got in the car after driving it, started the car and it fires for about 1/2 second and then dies. Try to restart and nothing, nada, zilch. You are stuck.

+1 Exactly what happened to me.

Anyone know -- Does the fuel pump come with a new blue rubber gasket/seal ring? The level sender unit I recently bought came with a new one, but it seems the pump may not. If not, I might just reuse the old one, since the old one on my sender was still fine.

Most pumps do not come with a new blue sealing ring. If you check out the pump found HERE (the genuine BMW pump) you'll see it exactly as it comes and note it does not come with a blue sealing ring.

And you can get the seal ring here.

What blue seal ring? Just did this yesterday and reused the black one that was already in the car. No blue rings anywhere.

BTW, that OE one on ECSTuning do seem to include the black ring..

I think the "blue ring" is the same as the black ring and is simply the fuel pump gasket. I also re-used mine with no ill affect. Make sure to seat the ring in the hole first, THEN drop the pump on down, if you try and put it on the pump first, you will drive yourself nuts.

That was the only problem I had, but then I asked someone who just did one and it went in very easily. You may want to use some ATF fluid on the ring to aid in the installation.

Good to know lol since I'll be doing this soon I think.

+1. In the video posted earlier the ring is seated first in the pump and it's installed put as such. That will not properly seal the pump and leaks will develop. Ring around the rim of the hole first, then drop the pump on top of it!!!

You're lucky to get 150k. The fuel pump on my car died just before 80K while cruising down the freeway with a full tank. I coasted to the side of the road and smacked the tank from under the car. A tow truck driver's trick that was enough to make it the remaining mile to work... where it died permanently. I changed the pump in the parking lot and the fuel filter later.

I got 163k now on the original pump. I just ordered one from Max - I wonder how many he's sold this week.

Mine died this winter at around 170k and yeah it was a 1 out of 10 for difficulty... I limped mine about 150 miles after the first symptom but only because I didn't have another good option. A good whack to the backseat can wake up a tired (near failing) pump, as mentioned above.

Group buy anyone?

OMG. This thread is starting to sound like a bunch of women wanting to sync their menses....


But ya, you got me thinking about changing mine too.

Oembimmerparts has by far the best price I could find, but you all could have guessed that.

there are cheaper options around.

likewise.

I just finished a successful fuel pump DIY
As a future reference for those whom have yet to do it below is two part DIY video was very helpful. (Technically there are three parts, but you only need parts 1 and 3)

Part 1: Starts at 3:20


Part 3*:


*part two not applicable

Mine just went out...no prior warnings...at 142k miles! Replacing it over the weekend. You guys are 'on the money' on this one.
Saw this and took it out of the shop before a $660 bill slid my way.

Thanks
