My fuel pump (NORS 4657) collects a several drops of oil after an engine run. I can't seem to locate the source by cleaning & watching, but I do find oil in the cavities of the top casting adjacent the attaching screw holes. If you look closely at the picture below, you can see motor oil in the cavity closest to the engine, front side. This picture was taken after 20 minutes of driving from a 'clean' condition. The aft cavity closest to the engine also has oil, but this does not show up in the photo.

Using a '63 shop manual for troubleshooting, it lists the pump oil seal, the plate/or pump gasket, or a hole in the diaphram as possible defects. I'd like to hope it is the gasket(s) and that the fan is blowing it around. Has anyone experieced this? Wondering if this is something that can be pushed off until fall/winter chores time.
