I remounted the right wing main and aux fuel tanks. Every time I remove and reinstall the tanks, they end up in a different position, despite leaving the top straps in the same position. Since I've already cut-out the filler neck hole, that's a constraint that has to be met. I used a small C-clamp to keep the filler necks centered in the holes. I had to enlarge the holes (again), so that no possibility of rubbing will occur. I used brass nipples to extend the fittings away from the rib to minimize the hole size. Caterpillar grommets seem to be the best way to protect against chaffing.
