Unable To Locate Fuel Pump

After Doing Research On The Location Of The Fuel Pump On My 2003 E46 And How To Change It, To My Surprise After Removing The Metal Lid That Covers The Fuel Pump Shown On The Videos And Diagrams, Found The Fuel Pump Completely Unaccessible, Meaning I Did Not Have Direct Access To It.

There Is A Piece Of Steel Which Seems To Be Part Of The Frame, Can Somebody Please Let Me Know If The Gas Tank Has To Be Dropped ?

I Already Have The Pump However The Access And The Connection In The Car To The Pump Are A No Match To All The Videos.

This is a different year car but basically the location is the same. Just take out the seat bottom and remove the metal covers.

I was just going to ask the same question.

2003-2005 325i in CA is likely a SULEV M56 car.

Simple to figure out, look under the car and see if you have a black plastic fuel tank or a stainless steel fuel tank.

If stainless steel, the fuelpump/tank is about $6000, and no this is not a typo.

Hopefull you have less than 150,000 miles on the car, then it is covered under warranty, however, you will have to fight with the dealer as they likely do not understand the SULEV warranty.

Totally forgot about this possibility. Makes sense.

Another way to check:

What did you do?

The sound insulation can be pulled aside to reveal the covers, you are not supposed to cut anything to get to the fuel pump or the fuel level sending unit.

If the fuel pump is not where it is expected, then you probably have the SULEV. If you need fuel tank service with this model/option, then it is probably under warranty.

Will Check Into The SULEV Warranty.
Likely My Car Is An M56 Due That There Is No Direct Access To The Fuel Pump And Have Learned The Fuel Pump, Fuel Filter And Fuel Tank Are All One Component.

Thanks For The Info.

Is your pump dead, or are you just trying to be proactive and replace a $150 part before it goes south on its own?

I ripped out all of that crap from the back of the car.

You're crazy. I just spend a few hundred bucks to put insulation in my subaru. I couldn't imagine ripping it out.

I see you're in the SGV, I am too, if you're still under warranty, I'd highly highly recommend Crevier BMW, it is quite far but they are way better and much more knowledgeable about the warranty than Assael/Monrovia and New Century BMW.

SULEV. OP, as said, you, have a 15 year/150,000 mile warranty on your emissions related components. So, if you are under 150,000 miles, you are covered. The dealer is going to have no idea what you are talking about, so go in with the warranty info, and clearly know what is going on prior to going in, if necessary contact BMWNA, in fact, probably contact BMWNA prior. There is a PDF floating around the internet that discusses the E46 SULEV warranty. Definitely print this out. If you are over 150,000, one user on the forum has successfuly retrofitted a standard fuel system into the car. But not advocating messing with any emissions related components for street use, because that would be illegal. Also, are you sure it is the fuel pump that is the culprit? Crank but no start? Check the pump relay first. Also do you hear a buzzing when you turn the key to position 2 prior to starting? If relay is fine, and no buzz is heard, then yes, very likely the pump.

Car Sometimes Does Not Start On The First Turn Of The Key, Will Have A Start After I Turn The Key On The Stand-By After I Wait A Few Seconds And Will Start With No Hesitation. Car Is Now Misfiring, Has A Major Loss Of Power And Idles Hard.

Misfires can be other things too such as vacuum leaks.


I've been wondering something: can a SULEV car be retrofitted with a non SULEV tank and fuel pump?
