Adam,
Congratulations on you and the family's first GMC adventure. Glad it
worked out well.
The small fuel drip at, apparently, near the left front of the aux (front)
tank, is very likely coming from the Liquid-Vapor Separator, or its
plumbing. You probably recall from when you re-plumbed the fuel tanks that
there is a hose from each tank which leads to a tee in the forward end of
the left rear wheel well. From the tee there's another hose up to the
little canister behind the sheet metal shield near the top of the wheel
well. From there, there's another hose leading down and eventually to the
carbon vapor canister on the frame rail beneath the passenger's feet. Any
of that plumbing, with its numerous connections, or the vapor separator
itself, can leak. Usually not badly because there should only be fuel in
those hoses when the tank's completely full+.
The best solution for those sewer line problems? A macerator. With that
installed above the bottom of the frame, you can move the 3" dump connector
to a less accessible/damageable location. Not to mention the many other
benefits, such as eliminating the "stinky slinky".
