A few notes for anyone attempting this.
You will have to free the clamp and black fuel hose from the sender. Any pressure applied when trying to free the hose from the plastic fuel sender will result in the plastic breaking off in the hose rendering the fuel sender useless. I found this out the hard way today.
Also, once you get the sending unit out of the tank, how do you properly disconnect all the hoses from the bottom of the sending unit?
......You have to disconnect the lines from the fuel pump on the other side of the tank, so you can actually pull the fuel sender out to try the JB Weld solution...
Hope this helps save others some trouble....
It is off to my independent to get a new fuel sender!

As long as the jb weld is applied correctly. That means it has to be very clean and dry. Jb weld mixed properly and put into the sender entirely. This will clearly work and solve the dreaded fuel smell issue many of us have.
Thank You for your contribution!

So was the gas smell only present during hot days or anytime you put gas in it? I just got into my car today while it was sitting in the sun and it smelled, but when it's in my garage I have never smelled it.

After months of owning a high milage E55 (104,00 on '04), I just got this leak.
it happened the same day I stupidly ran out of gas. It can't be a coincidence, but has anyone noticed a connection?
Anyway, this fix looks very promising. I would like to do it without removing it, especially after seeing Fasn8n's pictures. Why does the angle keep it from being done in place?

Any update on this? How has this fix been holding up?
I am getting my Tank, sensor, and senders replaced. I am thinking of throwing some jbweld on top of the senders just for good measure.

Im just doing mine atm.
Imo you cant just brush it on thinly on the pump side as mine cracked where those two prongs go down to the pumps on the top side you need to pretty much cover those two protrusions totally with a decent thick amount i reckon.
And cover the bottom bit of the plug as you can see where its laminated in there.
The sender side you might be more likely to get away with thin coats especially if its like mine and not leaking on that side.
If you look at the pics provided in this thread its pretty clear where it has to be covered.
Also i used a soldering iron to melt the cracks closed and sanded the pump side surface as best i could. Should be pretty good i hope.

ULike most of the E55s my suffered the "gas tank" problem. After replaced the pump by the dealer, the problem came back about nine months later. Not fueling the car all the way up helped, but since last summer I can't even fuel my car more than half full.
The problem on my car is the sending unit. It's the driver side one. I took it out and filled the unit with JB weld. I tried to cover the whole top of the assembly with JB weld. I also filled the passenger side unit with JB weld too. While I have both of the out I also replace the seal. The old seals are black, the new ones are green. I did this last August and until now I have not have any problem with the gas smell.
The reason I report this now is the last couple days the weather were in the 80' degree range. I checked the pumps and they were bone dry.
JB weld ~ $20
Two new seals ~ $50 from the dealer
And a small worm clamp, that's all I need to fix my problem.
Also if you decide to do this, please run your car down to empty, let the JB weld cure for a day before install (this depend on the thickness), and try not to get any JB weld on any of the plugs/connectors. Good luck.
I put on about 5K miles since the fix. Also I have a brand new MB sending unit if anyone need .

... following this DIY may have helped you... although the pics have disappeared for some reason. Always CUT the line, cheaper to buy fuel line than to break off the plastic.
