After reassembling the fuel system and pressurizing it overnight, I found the return red cube inlet leaking. Disconnected it and discovered inlet fitting had a small gouge in it. Replaced inlet nipple and left Permatex#2 to set up before testing.
Installed resized 1/4 turn fasteners in aux fueler filler doors.
Started working on the initial cowl trimming. What a pain!! Just tring to figure out how to measure it is interesting.
