Thanks Michael;
  I didn't think of just coating the fiberglass tank with something.  So a bit of research came 
up with the two best choices.  According to one newsgroup, (therefore not necessarily a 
reliable source but a bit better than no opinion at all), the #1 favorite is:
1.  KBS Gold Standard Tank Sealer - "... it will form a super-tough, fuel and alcohol 
impervious coating, ... Gold Standard may be used on steel, aluminum, and fiberglass 
tanks."

  I talked with tech support at KBS and asked specifically about ethanol and explained that it 
was for a homebuilt aircraft fuel tank and our lives depended on the sealer protecting 
against the erosion caused by ethanol and he said he was positive that their tank sealer 
was for all fuels including ethanol.
