Sometime what happens when replacing a fuel pump. The gasket that seals the Tank with the fuel pump assembly gets folded over or misaligned when putting the fuel pump assembly back in.

Problem is theres not much room to see what your doing when putting a fuel pump assembly back in when your working on a sedan because of the back seats. No problems with Wagons though, you just fold the seats forward and sit in the wagon space.
