When my fuel tanks started to show signs of damage I researched Vinyl Ester and found a manufacturer of underground pipes and tanks for gas stations.  http://www.fibreglast.com. product  1110/69-A
I bought a gallon and built liners for my new tanks with it. Details can be found here http://forum.canardaviation.com/showthread.php?t=4594

That was three or four years ago.  I have seen no degradation of the material.

Lynn,

 

   It has also been my understanding that the Vinyl Esters were more resistant than many Epoxies to fuel (particularly auto fuel) but

do not recall discussions on this forum about  testing of the various Epoxy or Vinyl Ester  formulations in auto or 100LL fuel over

a long term............

Are not the under ground storage tanks made of fiberglass re-enforced

Vinyl Ester? The new fuel blends cannot attack whatever that specific compounding is involved there.
