How about making your own tires!

And for anyone that did not check the price, BMA parts should still have the pump/fuel sender assembly for around $125? I think some have found online import parts suppliers that may have a similar pump/sender for around $100.

For something that will leave you stranded, $125 is a no brainer in my book.

I have had a pump for my wife's 2006 E46 vert that has just over 60k miles in stock for over 6 months. I just need to decide when I need to make the move to install it. If my wife gets stranded, it will be WAY more than $125 of guilt, grief and lack of affection!!

Make the swap a 20 minute job if you all the tools and the seat out, no fighting with a pump that does not fit the sending unit. Also if you do not get things right the pump will be noisy.
Thanks anyway, I think I can spend my own money, or not....thumbsup:

Oh, BTW. It's only a 20 minute job if you replace the insert on the pump, 10 without. Been doing this for years.

Not sure of the supplier/pump manufacturer, but BMA Parts has this listing currently on ebay for $69.90 shipped for a pump/sending unit assembly.

Guys, keep in mind my car was babied and a very clean and well kept up car with absol. no dents and interior blemishes when I got it @ 115k and driven smartly, but harder than its previous owners I am sure for 25k by me the past year.

So, point is i made it to 140k on a easy driven e46. Don't take bets with a car that looks like its in worse shape. For the record my girl just sold her e46 @ 130k three days ago, and its been beaten to **** and up until 2000 miles ago had orignal fuel filter, and she still was on the OE pump. Hers was a 02/02 build mine is a 03/03 build and has had regular filter changes its whole existence. Mine dies @ 10k more miles then her beaten e46 who has, I am sure, been ran around when low on gas consistently more than mine !

Go figure.

Point is there is no figuring!
Way far too many variables than we know how to factor in.
Kinda like thinking you could possibly claim there is global warming.

No I'm sending the defective one in and they are sending a replacement pump.. It went out on a 700 mile drive so I had no time to deal with the bull **** at the time, so I had to overnight one.

Hope I didn't come across as a d!!k. I've been doing this for a long time mainly out of necessity, $75 for the electric pump insert vs. $400 for the entire pump. But looking around, the prices for BMW assembly's are more reasonable than the Saab and Audi ones I'm familiar with.

My car is throwing up codes for misfires in 4 cylinders, all at the same time. I haven't tried switching my coils around or replacing spark plugs because i doubt they would go all at the same time. Is a fuel pump more likely?

So I have been around this forum and many of the other BMW forums and what seems to be a reoccurring theme is after about 7 years is most of the E38, E39, E46 and other similar vintage BMW's not newer than 2006 are have failing fuel pumps at a very high rate. Probably a rate of about 100%, as I say its not if, but when!

So a word to the VERY wise, if you have a spare $150 or so and a couple of hours, order yourself a replacement fuel pump, new fuel pump relay and fuel filter and replace them as a PM item.


Do not say you have not been warned!

Denial is not an option, as you will get a rude dose of reality.

i have an issue with my vert 323ci ... i dunno if its related to the fuel pump or not but i think yes.

a couple of weeks ago i started my car and it hesitated to start after i filled it up with gas.
but when i got the car on the D and stepped on the accelerator the car died on me. i started the car again and the same problem happened like 2-3 times and bam the engine service soon light came on for a couple of hours and went back off again.

happened few times with me and the last time happened was yesterday when i tried to start the car and all this happened and i felt like the car is not getting enough gas .. so while i was on P i stepped on the gas and i went up till 5 RPM, and then i stopped , when it got back to 1 RPM the car died , tried it 2-3 times and same problem and the service light is on since then .

i know this is too long but is this related to the fuel pump/filter ?? my car only got 109k miles on it .

any ideas ?

The 2000 cars seem to have pumps that last a bit longer, but look at it this way, fuel is a very important part of the engines ability to run and run properly.

You car is 13-14 years old at this point. You make the call as this point.

How old is the fuel filter??

BMW says they should be changed every 60k miles, a smart person would change them at 30k miles.

Also suggest you read the first and 3rd link below in my signature as well.

Do you have a CEL?? Do you have trouble codes?

Do you have a tool that will display fuel trims and real time data?

This will go a long way to helping understand what may be going on.

it could be a number of things including the fuel pump. first thing to do is scan for codes.

Anyway to tell if it's been replaced?

Hey guys,

I'm afraid my post might get a bit buried in this thread, but the question is an appropriate reply...so, here it goes...

Just purchased first bimmer...2001 325i, 117K, one owner. Terrific shape...this is my first post, so, I'll get newbie pics up soon! Actually, bought for my daughter's 16th birthday...will drive it about 2 miles a day to school with a little extra on the weekend (I plan to get my fair share of seat time in it).

Anyway, is there a way to tell if the fuel pump has ALREADY been replaced by the original owner?

Thanks and I apologize if this is a stupid question....I will be spending quite a bit of time here, and I look forward to it!

Greg

Yes, remove your seat and see how badly the fuel pump ring is stuck on and how dirty it is. That is a major clue.

Also another indicator is if the rubber sound mat has not been cut, you likely have the original pump.

Make sure you plan on a fuel filter soon as well.

Suggest you read the link below in my signature for other things you need to prepare yourself for.

Also read this link - http://forum.e46fanatics.com/showthread.php?t=967204

If you do not have a OBD code reader, you WILL need one!
