1968 Dart Fuel Pump question

Hi,Today I was driving the 68 Dart and started smelling gas really strong. Pulled over and lifted the hood and saw that gasoline was leaking out the weep hole above the diaphragm,so the fuel pump is bad and needs to be replaced. Drove the rest of the way home and picked up the pump to replace it and was wondering,will I need to do an oil change now too? (I just did one two weeks ago). Does the gasoline leak into.the oil when the diaphragm leaks like this? It's funny that the car ran fine still with it leaking gas the way it did.
