Measured and final cut/flared the fuel line to the firewall. Added nut plates to the seat pans for the mounting structure. Then final mounted the fuel pump and red cube, attaching the fuel line between the two. Also final mounted the nipples and fuel filter. I am using Bakers seal on all NPT fittings. It is supposed to be excellent in all areas for all fluids we see in our planes. I guess we'll find out, eh?
Fuel line final cut and assembled.
Seat pan nut plates. Pans overlap so I added a shim to the structure I made.
I don't intend to take these off again for a long time....
