BB oil pump leak

my5thmopar said

I have a slight oil leak somewhere around the 440 oil pump. Unknown pump age. Is this just straight forward remove and replace? Never done one. Do I need to worry about any sort of alignment with distributor? Also, should I just replace it? I can get a Melling M63 cheap though my commercial account. BTW this is the D100 project, so nothing in the way Craig

You can also order the gasket and O-rings to reseal the original pump, but installing a fresh pump is a better solution.

Be sure to disassemble the new one, debur the parts and clean them. Some folks fill the new pumps with vasoline in place of priming them, but as mentioned above spinning it with a drill seems better to me. No need for a high volume pump with a stock motor and pan. The MV 63 is a high volume pump isn't it?

The pump can also appear to be leaking if the valve cover above it is seeping oil.
