Woot Woot. Turns out fuel fill hose (1.5") was pinched tween inner and outer hulls. It was 30 years hard, and so it simply bent over and freed itself when pushed. New hose went in easily. Bow light wires now run through the coffin, along with fuel sending wires, and static ground for fuel fill. I will put some fuel in it to make sure nothing leaks, then put the coffin lid back on. Woot woot!
