Default leaking some fuel

So I started smelling fuel and saw a small puddle Got to looking once I drove it home and it is dripping off the bottom of the vp44 out back toward where the lines come out. I can't tell exactly where because It's kind of crowded back there. But it feels like it's coming off the bottom of the pump. Truck still runs and starts great Checked all my lines they are good and tight. Is there anything else I should try. Can I buy one of those ebay seal kits and fix it or am I screwed??

Check the lines up by the injectors to see if it's running downhill from one of them. Sometimes if the seal isn't exactly lined up the compression fitting can leak a little even if they are tight.

Are all the little blue connectors still in place and in the right places on the fuel lines.

Ya there isn't any fuel running down the lines that's the first thing I checked since I ha djust done the injectors about a month ago. As for the return line I looked it over pretty good and can't find anything.
