What causes gas to leak into oil?

How does a mechanical fuel pump allow fuel gas to get into crankcase oil?
Mechanical fuel pumps use a lever that rides on the camshaft to pump a rubber diaphragm inside the pump up and down. This creates suction that pulls fuel into the pump, and then pushes it along. A pair of one-way valves inside the pump only allow the gas to move in one direction (toward the engine).
