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.
