Had my DB pump rebuilt around a month ago at a local diesel shop.I noticed a leak today that appears to be coming from the area i have outlined in blue. This is the same spot it was leaking from before the rebuild... It didn't appear like it was coming from the injector line screw/washers. Anyone else ever had their pump leak from there like this?

If it's not one of the line bolts, could be a bad head O ring or a
bad spot in the housing where the O ring makes contact.
Make sure leak isn't at one of the back lines, and coming
around the front side since pump sets at a slight angle.
