E30 (1982 - 1993)
God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

Gas spilling out filler tube on left turn

I have a 1988 325i convertible.

Here is a good one for you'll: After I fill the gas tank and I make a left turn gas spills out the filler tube. I tried installing a new locking gas cap but it didn't help. There doesn't appear to be any hole in the filler tube.

I am wondering if anyone else has had this problem and might suggest a fix.

Thanks in advance!

There's a crack in the hose that goes from the filler neck to the tank.

No, it is spilling out the top of the tube between the filler cap and the tube. If I drive about three gal. of gas it stops spilling. I think there is a part missing at the top of the tube to stop the gas from spilling but I am not familiar with the BMW gas filler tube, as I am relatively new the car. PS: I really love this car. I wish I would have purchased one years ago.

Actually, no it is not missing, but that is a good question. I'm not sure, but I think there is suppose to be a small aluminum spring loaded cap that fits in the tube and stops gas from spilling out. There is a similar device on my other cars. I'm not sure if the BMW is similarly equipped or not. If someone could look down their gas filler tube and let me know, that would help. Thanks!

I stopped by a local salvage yard and checked out the gas filler tube of a similar car, and there is a little spring loaded seal that the nozzle of the gas station filler hose opens when the tank is filled. Mine has apparently broken off and fallen into the tank leaving the filler tube open to spill when I make a left turn and the tank is full.

As to fixing it: I believe I will have to replace the whole filler tube to the tank. I suppose I could cut a length of the tube off and replace it with a similar length from a junked car and clamp a rubber hose to seal the splice. As for now I will put a stopper in the hole and hope it fixes it temporarily.

If anyone has a fix, I would be happy to hear it. Thanks!

Use your best judgment wherever` safety is concerned, ..probably best to replace the complete un-modified tube assembly with either a new one or a used pipe in good working condition with an intact flapper valve, than to risk dropping anything more into the tank or worse...more leaks

Sounds like good advice. I am not sure how much it would cost. There is a good pipe on a 325ix at the yard. I don't know if it would fit, my 325i, or if I could remove it. Do you know if it comes off in more than 1 section?
