As said my car is leaking, and car is smelling like gas, took the back seats off and saw a few cracks and gas leaking through the cracks. What is this part? I thought it was the fhelt pump but that's on the passanger side, what's on the driver side under the back seats? It continues to leak, I was wondering if JB weld could fix these cracks? Or the name of this park? What does it do.

Thanks!

I believe it is the fuel level sending unit. In any case run the gas down in your tank before you try and replace it to at least a 1/4 tank or less.

It's this. I have same issue on my 335i. Picked up part and running gas level down below 1/4 tank as suggested.

Just had the same issue on mine; ordered part but now have to find the ring lock tool to open up the tanks (-_-)

Fuel-it.biz has them.

You can borrow one from Autozone. They charge you for it and when you bring it back they credit your card. Free! I just knocked this job out this morning. There is a DIY on YouTube. I highly recommend running your tank below a 1/4 tank. It makes it a lot easier.

I found a hammer and a flat head screw driver. My wife filled up the tank but it was still doable. Very easy job.

Where do those 3 long hoses go? I got my part today and when I opened it up, it scared the hell out of me. No instructions.

You need to remove the fuel pump as well. 2 of the black hose go on the side clips and only 2 snaps on the top area of the fuel pump.
