1966 170 engine fuel pump oil leak

[towood]

66 with a 170 six. Old fuel pump was leaking motor oil, likely from the top half of the pump (diaphragm that runs the wipers)

Replaced with one from toms broncos and it has oil weeping from the same spot, top diaphragm.

Is this a known problem? Is there a brand out there better than others?

Did you clean all the oil out of the lines connected to it before installing the replacement?

Hi, check the dip stick. If fuel and oil were mixing you could have a lot of gas in the crankcase. Good luck
