When I looked into epoxies and mogas 
compatability - 10 years ago, before ethanol 
started showing up - the epoxy with the best data 
was WEST.  Since it's used primarily for boats, 
and boats use mogas, they had 20 years of fuel immersion data.

I don't have that data for the current fuels - 
but if someone were to contact Gougeon, I'll bet 
they're still doing ongoing tests.
