Hi all,
My fuel drain valve flange came with countersunk holes.
The plans calls for size AD 426-3-4 rivets but the countersinks are too big.
Size 4 rivets seem the perfect size for these countersinks.
I will then drill to 1/8" so the manufacture head sits tighly on the flange.
Anyone else have this issue???
