Cant pinpiont it exactly but it drains off the very bottom in the middle of the pump it pours when its cold out and drips when in warmer weather. I guess the seals shrink when it cold, and then theres a small leak on top where the line from the ksb goes

On the back side of the pump opposite the KSB is a small cover held by two Torx screws. This is sealed by an O-ring. O-ring is probably blown (pretty common). Removal of pump is required. Use only an o-ring from a injection pump shop, parts store ones won't last.
