WTB--Fuel sender sleeve

Drew, what do you have for venting anyway? Best to do what Steve did and convert to the Euro style and vent the filler neck out the trunk floor.

The grommet for the trunk floor that holds the tube in place and helps prevent the fumes from wafting back into the trunk are still available.
 
The trunk floor grommet looks like a funnel. I installed that over a year ago. At the Homestead Speedway Brian Redmond Targa with the Everglades BMW CCA chapter, we had about 30 minutes to drive the road course. The BMW behind me told me I had gas leaking from the back of my car. That must have been gas sloshing out the vent tube on hard left-hand turns.
 
Maybe gas cap....

Gas cap issue

I have a 71 2800 Bavaria i purchased a new cap a couple of years ago. This week I noticed when I take the cap loose a lot of pressure is released from the tank. Do I have the right cap? Are ther different caps for different years? Thanks for your help

The grommet and hose going out bottom of trunk is for use with the Euro system that Steve mentioned above. It vents from just below the fuel filler neck. I can't imagine gas sloshing all the way up there and down the little tube even when driving on a track. But of course my imagination is little match for actual physics.

My CSi had horrible gas fumes in the trunk. I replaced the vent hose, floor grommet, fuel cap rubber gasket, and both rubber hoses going from sender to fuel pump and hard return line respectively. Everything is great now. I think I also replaced the gasket on the fuel sender, but would have to double check my packing lists to confirm.
 
Dan--I agree with your thoughts about the gas traveling up and out through the vent . The car behind me said the gas was coming out where the vent grommet is located. But I don't know where else it could have escaped. I hope that replacing the fuel sender gasket solves the problem.

I routed the tank vent to the expansion tank and then through the floor instead of directly to the floor.
This might prevent the fuel dumping that @Drew Gregg is experiencing.

Dan--I eliminated the vapor tank and the bracket when I finally got the elephant ear spacer. That's in another post. I'm just concerned about the gas smell in the trunk when I open it.
