Fuel Pump Location

Brockmeister · 07-03-2012, 07:07 PM

Hi Class. Where is the fuel pump located on an '04 325i? Mine crapped out today and I ordered a new one from BMA. Is it under the passenger seat or do I have to drop the tank? Either way, It has to be fixed.

Let me get my easy button... Its under the rear bench seat, its easy to get to and an easy DIY... You should be able to use google and find the steps to the DIY. Just my two and a half cents worth!

Do you have a SULEV engine by any chance?

325guy · 07-03-2012, 07:38 PM

the SULEV engine is for the birds

No. I have the normal engine. I was in the fast lane on 95 and went to accelerate. My foot went down but the car didn't speed up. I parked it on an incline at my house on Thursday. I went out this morning and tried starting it. It coughed and weezed...and then died. 124,500 on the clock
Thanks All

Access to it is literally under the passenger's seat. Easiest replacement ever compared to most cars.

Brockmeister · 07-03-2012, 09:29 PM

sounds great. I've had to do it to 2 Porsche 944's, plus a sending unit. They're somewhat similar. My '98 328i had 150k on it and was still doing the job before it got wrecked,

So I'm guessing you're not hearing your fuel pump prime for a few seconds immediately at start-up? If you're doing the job I would suggest replacing both sides while you're already in there...

Both sides?

You do not need to replace the siphon pump on the drivers side. This is a passive device with no moving parts. Very rare these ever have problems.

I did read this earlier today. Got my fuel pump from BMA for 106. I knew that was the problem after I read a few posts this morning. Fule filter was replaced last year. Hopefully the relay isn't bad, but if I find out it is, I get a new one. don't need the car for a while. Have plenty of time and other things to drive.
BTW: thanks for posting all the good info.
