E85 in 160psi water pump for HFS/2/3/4/6 and E85 versus meth?

[Martin RS8]

Can all parts and seals in the water pump handle E85 fuel ?

I know that other brands don't work with E85 because it is 15% gasoline and 85% ethanol.

Does anyone know how big difference in performance and cooling capacity it is between:
50% E85/water mix
against:
50% Methanol/water mix

Pretty sure that Richard has said no petroleum in the pumps, but I will let him have the final word.

My understanding is the methanol will cool better than the ethanol, especially after the seals in the pump spraying E85 swell and render the pump useless.
