Both fuel tanks were retrieved and appeared to be intact with no leaks and still felt full of gasoline.  Both fuel fill ports appeared intact.  1 tank still had the original fuel hose dated 1987 attached and appeared in good shape with a fresh tear on the end that attaches to the fuel fill.  The blowers switches had been removed from the dash, but it is unknown if they were detached from the explosion or salvage removal.  The port motor had an attached carburetor flame arrestor with the plastic cover still attached.  The starboard motor had an attached carburetor flame arrestor with plastic cover still attached.  The starboard motor had an attached carburetor flame arrestor but the plastic cover and nut that holds it to the top of that were missing.
