Hey everyone,

I had to change out the fuel pump and the plastic ring on the neck of the tank basically broke. I can't seem to find that part anywhere and BMW says they don't sell it separate or even have a part number for it. I've been scouring the net for it but it seems the only way to get it is to buy a new tank. My tank is good, I don't want to spend hundreds of dollars on a $2 piece of plastic. Can anyone point me in the right direction? Is this a common issue on the tanks? I've attached a picture to show the part I need.

Oof. How did it happen? How were you removing it?

I don't know how the ring is set into the tank. I'm guessing it's clipped in somehow. Yep, you're right, there is no separate part for it. You'll need to find a used fuel tank and try to remove it.

Will the metal collar still lock in, or is it completely broken?

All I can find is this for the E60:

Hey OP quick update. I found this:

It's a fuel tank pump support ring for a BMW motorcycle, but supposedly this is a relatively universal part. People say this can be used on the E46. Maybe it'll work on the E90 as well? Worth a shot for $10.

Also give the people over at Fuel-It! a call. They know these fuel systems inside and out.

Let us know what you find out. Hopefully you can get a cheap solution.

You piqued my interest. I dug into that part to see if the diameter was listed; it wasn't. It only fits motorcycles. There is a matching "cap" used on the level sensor for motorcycle tanks. The cap P/N does cross over to the E85/E86 Z4; maybe that's where the E46 cross reference comes from. I'm not sure the motorcycle support ring will fixed the OPs problem.

Looks like a trip to the junk yard...

That will be easy and cheap to get at a you pull it yard. You can search for pre-lci cars at the links below. Run the vins to make sure they are not N51 engines as they have a different tank.
