Cindy was so kind to prime the little spacers so that I could spend my time today in prosealing the naca vents to the fuselage.

The advantage of having some rivets is that you can use the cleco's to clamp the naca against the skin so there's no need for extra clamps.

Wing tank construction is so long ago that I completly forgot what a mess this proseal makes.

As I had some time left, I also rivetted the small nutplates that came in from aircraft spruce Europe on the fuel pump support brackets.

Some hours later went back and rivetted the vents using the aluminum spacers.

Some more work done on the fuel pump. I drilled the holes for the doghouse cover. See the nutplate templates on the images below.

Then dimpled, deburred and installed the nutplates for the doghouse.
