Fuel Leaks when I fill up the tank

Hello everyone,

First off I want to say thank you to everyone who contributes in the betterment and guidance to these chariots.

I have a 1990 325i convertible. I recently replaced my fuel pump and when I filled up the tank to full I noticed a great amount of fuel leaking underneath the car. I rushed home, luckily I was not too far, and made it safe. Once I got home I disconnected the battery, removed the back seats and decided to look at the housing for where the sending unit is located. I unscrewed the top and the foam was soaked in fuel. I lifted the sending unit and of course some gas was coming out so I quickly put the piece back in. The moment I did, fuel was coming out underneath.

My question is, could there be a crack in the housing? Or is there are another problem. My apologies for my lack of understanding still learning.

Any help is greatly appreciated.

Thank you,
