Oil from Vacuum/ Fuel Pump

[Mud Diver]

So, is it common for the combo vacuum fuel pump to spring an oil leak at the vacuum diaphragm? Or would mine just have loose screws?

yea, btw, I know I have a loose screw

Both of mine leak after rebuilding lol, granted I haven't gone back over and checked for loose fasteners yet.

I would think a loose mount bolt/screw would be the issue for an oil leak at the fuel pump.
