Hello,
Mechanical fuel pump can leak oil around the mounting area.
Typically, due to bad gasket.
Best course of action would be to inspect the fuel pump mounting area. Usually with oil leaks it is easy to tell if it has been leaking.
Keep in mind that the valve cover gaskets can leak as well. The best way to tell is to inspect those areas. You can also use oil dye, which can help you find leaks easier.

Please let me know if you have any questions.
Thank you.
