Fabricated line from pump manifold to firewall penetration. Wrapped lines in spiral wrap and electrical tape to prevent potential chafing. Reinstalled lines and pump to fuselage, leaving line from selector to manifold uninstalled to facilitate system purge. Installed Engine Pod on firewall, using nutplates, screws, and 1/4" standoffs to enhance cooling and provide clearance from universal head rivets on firewall. Inadvertantly misdrilled two screw holes; filled them with 3/16" rivets and sealed with high-temp RTV.
