Gas leak

So...close to year ago i fill up tank on my e46 2001 325i sedan...goto store...

Come out adn find gasoline POURING out over rear axle...like a hose was running....

Lose half a tank....come to find i can fill it halfway no prob..maybe 2/3 but hit 3/4 and it would pour out.

Ive been told to look at tank would require dropping it to look at top part etc...and to drop tank means dropping exhaust...which means $$$$

fast forward to 3 days ago...wife take s my car...and FILLS TANK...she never fills her car even when lite on but....anyway...didn't leak?!?!?!

Any ideas? car has no ( obvious ) rust on it...almost down to half a tank now no leak...

thanx

Have you done a visual inspection? Some of the fuel hoses, or connections might be loose at that 1/2, 3/4 level around the tank.
It can't leak from the top, that doesn't make sense, the shop must have said that to make $$$.

You didn't say, however, that can happen when the fuel pump is replaced, and the rubber seal is installed wrong, so it doesn't seal. Have that done recently?
