Back to the fuel valve. I had to order some 3/4 x 3/4 angle for this mounting. The andair valve is really slick, but to mount it requires a bit of fab work. I cut and trimmed the front mounting angle until I got the fit I wanted. Drilled and clecoed this angle into the F844L aux. longeron and the F878L mid cabin brace. This angle will be riveted in place. Cut and trimmed the rear mounting angle—drilled and clecoed this angle to the F878L. I want to drill the mounting holes for the fuel valve before I drill this angle to the F844L longeron. This angle will be mounted with c/s screws and nutplates so that the fuel valve can be removed in necessary.
