Here you can see the safety wires that secure both tanks. The delrin boom tube clamps on the rear boom tube were tapped for 4-40 cap screws and an eyelet was added in front for the line to pass through. I use 50 pound test nylon leader and stainless crimp fittings to form the loops at each end. Sure beats losing a set of Walt Barney tanks if the cowl comes off in a mishap.
