Fuel Pump
 

So my X5 is getting some miles on it and its pretty old so I want to do my future self a favor and replace the fuel pump before it strands me somewhere.

I just can't seem to figure out who the original supplier was; I know for the E46 it was Siemens/VDO. Spending $300 or so on a Genuine BMW pump makes me cringe.

Where do you guys get your fuel pumps?

Thanks.

The one I pulled from the 4.6 was a Pierburg.

I used a bosch pump on my E34 when I replaced the pump. Here is a link to the American bosch site:

Simply add vehicle and pick your part.

When I replaced the fuel pump in my E34 it was the same part number as a VL Holden Commodore (Aussie GM car). I found that by shopping around and buying the new part for a Commodore was a whole lot cheaper than the same part for a BMW, even though it was exactly the same part.

Look at the cross compatability as often vehicle manufacturers use the same parts as other vehicle manufacturers.

I use BMW Parts and BMW Accessories | Bavarian Autosport a lot. You should put the year and engine of you X5 in your signature. No knowing what you have for my X5 the offer the BMW version and also one by Delhi that is half the price. I haven't heard anything bad about the Delphi version.

I wouldn't bother with the Oreilleys/Autozone house brands but Pierburg, Siemens, VDO, Delphi are all OEM suppliers. I wouldn't hesitate to use any of those. I've seen them on ebay and amazon for as low as $260. As such a critical component and the peace of mind a quality replacement would provide, I'd even take it at 400 with a smile.

The one came off my iS is Pierburg. You don't need the whole assembly, just the pump.

For my '01 3.0i, it was part number 16-11-6-755-043. Pierburg (original) came out and a new one went in. Pierburg is now owned by TI Automotive, so don't worry if that is the brand name you see, it is still Pierburg. Cost around $180 on Amazon. I just replaced the pump, and re-used the plastic assembly/sender/etc.

For my '04 e52 3.0, I got a Delphi at an Auto Zone for about $145. All you need is the pump, not the whole assembly. You can re-use the structure, although it's a bit of a pain to get out the pump cylinder, but less expensive. There was also a 20% off coupon floating around on that site or advanced auto parts.

It's a fairly easy job, but take note and pics as you do it. Putting back the pump structure took several shots - again, take pics of the position of the structure when you remove it. Also, screwing back the top cover took several tries, as you have to rotate it just right. I suggest you mark the top position of the cover on the edge of the tank before you remove it, so you don't forget how it went.

Remove the pump from the white plastic brace carefully by pushing up on an edge of a table. Good luck

BY THE WAY: Pumps can go bad in summer if you don't keep the tank at least 1/3 full. Apparently, the gas keeps the pump cool, and if you keep running low, it overheats.

Believe me, when it's 110 degrees in Texas, it doesn't matter how much fuel you've got in the tank! My only replacement was done at 245,000 miles. And it was only done because the sending units were reading incorrect levels.

2002 X5 3.0 305,400 miles
2014 428i 19,700 miles

2004 325i sold at 123,600 miles
2001 325i sold at 66,000 miles

1970 Firebird - Under restoration

Still have the original fuel pump at 116,000 miles with all of that spent in Dallas. Always run the tank down until it says I have about 20 miles before it runs out.

I just did my pump as "preventative" at 186k miles, found original Pierburg on eBay about $185 with shipping, arrived in 2 days. It does not come with a new screen/net, mine was very re-useable but might opt to grab a new one. Can be done with more then 1/4 fuel in tank - read my post here for my tip on getting the pump to unclip from the holder: http://www.xoutpost.com/bmw-sav-foru...olved-yes.html

@ Andrebxp. I don't think you mentioned the year & version of your X5. Many put this in their signature, which is a great time saver and helps the group to help others.

I just had this happen (you'll see my model & year) on vacation. It was fixed by a local dealer, which was a VERY pleasant experience.

I asked the dealer tech, and service writer, who both drive similar cars (E39) and understood that I'm a serious DIY person. Whether diesel (my car) or gasoline (perhaps you), the in tank pumps are something that will simply wear out. I got nearly 280.000 km on mine - pretty good.

Should you do on terms of preventative repair, I say YES. When is your call.

What to replace to do it right?

(a) In tank unit (on right side of tank)
(b) Fuel sending unit (the part interacts with the pump to keep the tank full on both sides and scavenge from both sides).
(c) Specific (sky blue on my car) DDE relay that controls the pump (glovebox / dash area).

For diesel owners, there is a second pump under the car near the fuel tank, which I will be replacing myself this month. If you have a 218 PS car, the fuel filter is mounted in the same areas. Protective cover needs to be removed for this.

For 20 bucks more I would just buy the complete assembly and not deal with taking the old pump out and putting the new pump in. Less chance of breaking some of the plastic pieces that secure the pump.

I agree if it's just $20. But how does that $199 item compare to this $389 one from the same vendor, same regular price, same BMW part number?:
BMW X5 Fuel Pump Assembly OEM 16116755043

Typo? Part numbers are the same except for an A. Could it be that they sell the $199 one without a fuel pump? The $389 seems to be around what I was looking at as an option when I just bought the pump.

If it really is $199 for the Pierburg everything, that is a steal. Anyone considering doing the pump as pre-emptive repair might want to move on this if it is legit.

^yeah when I was looking, the pump-only is like half the price of the pump with float.

$199 is a steal!

.......sounds too good to be true

The only difference between the 2 is that one comes in a BMW box and the other one doesn't -

Pierburg makes the OE pump -

Similar to buying a front tension strut for $250 for "Genuine BMW" made by Lemforder, and Lemforder tension strut for $110 in a Lemforder box

Well, that explains it. Anything with a BMW logo is always worth more.

:bustingup

:iagree:
Only double the price? Must have been a misprint because the logo imprint is always worth 3X more.....

That was the Sale price. The retail price is three time more. :rofl:

am I missing something here?
On RockAuto its cheaper to buy a COMPLETE Delphi brand assembly compared to just the Delphi brand pump...
how does that math compute?

If you buy just the pump, they need to remove the pump from the assembly so there's more labor involved.

:bustingup

Who here has replaced your proactively....

After reading so many threads on this, I did mine about 18 months ago, just because. Went with the whole assembly. It wasn't that much more expensive, in the grand scheme of things

^^I'm about to do mine preventatively - for $200 - I already have a new fuel filter -

Might wanna crack open the other side and change the "o ring" on the syphon pump (this is what i read goes when it stops syphoning??), I wish I did this when I had the other side open, small part cost, and my hands already stunk of gas.

That's only if you did not replace the assembly. At 100+ miles I presume/assume for everyone who is changing them...makes sense to me to have fresh plastic than old. Besides, priceless to just remove seat, deadener, wire and hose. Remove unit and reverse.

I hate the stink of gas and it seems impossible to get the smell out once you got it on you.

has anyone here run a DELPHI brand pump assembly? It's $166 CAD compared to $199 USD. thats like $1000 difference in canadian :) just kidding but it is substantially cheaper really ($100CAD). BUT if bad reviews say so I'll buy a Pierburg.

Delphi is an OEM supplier. I even bought Delphi coils one time and they literally were BMW coils. The bmw logo had been ground off. I wouldn't hesitate to use Delphi and save some money.

That's my thoughts too Dean.

edit: So I bought it and I have a good feeling. I've always seen good products from Delphi.

Was redoing my drawers and came across the fuel locking ring socket I bought for this DIY....did not want to mess with potential sparks, screwdriver/mallet.

Anyhow, I have the Assenmacher tool. PM me for anyone who's interested.
