Received new stainless tubing to replace cowling side hinge pin aluminum lead in tubing that deformed when I tried to open it up. Bent to shape and installed. Need to figure out how to properly secure it and cut to final length. Sam retorqued firewall to engine mount bolts and secured with cotter pins. Began fitting cabin heat scat tube from inlet duct to heat muff. Removed inlet ducts to prep for paint and determine location of scat tube cutout. Started bending of new breather tube since old one interfered with oil cooler on firewall. Photo of tools used to connect two Adel clamps together to secure breather tube to engine mount.
