Primed all the doghouse parts with NAPA 7220 self etching primer. Once the parts were dry I riveted the doghouse together. Used the squeezer where I could, gun and bucking bar for the rest. Riveted on all the nutplates with the squeezer. Mounted the fuel pump and filter to the base with stainless steel hose clamps as per the plans. First attempt at making the fuel line from the filter to the pump did not turn out well. Second attempt went much better. Checked fit with doghouse and clearance is good. One fuel line done.
