Riveted the left and right F-1295-MOD Skin Stiffeners to the Fuselage Side Skins and the Firewall Shelf. Plugged the holes in the F-1201A Firewall Upper created by the retrofit with pop rivets. Reinstalled the Gascolator to the Firewall. Flushed (with compressed air) all of the fuel lines. Re-connected the F-1295C Fuel Line Floscan to the Gascolator and FT-60 Fuel Flow Meter. The Stiffener Retrofit is complete except for applying sealant to the heads of the newly installed rivets and 2 holes at the sides.
