Completed section 28 tonight by installing the last section of 1/4" return line to the front of the fuselage. Went relatively smoothly. Finally, loosened all the fittings one by one and added some Fuelube to them and then tightened them up. This whole section seems to be done correctly over the course of only 4 days (two longer weekend days), so I hope I don't find leaks or other issues down the road when I pressure test the system.
