Installed bulkhead fittings in bottom of fuselage for brake lines. Did more research into linking bulkhead fittings to Grove arfoil gear legs with built-in brake line passages and fittings installed. Made decision to fabricate loop line and re-clocked bulkhead fittings to accomodate design. Fabricated brake lines to run from center fittings to floor fittings inside gear towers; torqued and sealed.
