I'm going to install a clear sight tube so I can keep better track of fuel in my older Model 2. Looking into partially opaque inside wall of tank just doesn't hack it, especially when the fuel is low and the butt rib and some cockpit tubing are in the way.

So, I'll empty the tank and tap in a couple of fittings. How's the best way to keep the drill filings out of the tank?
