Word of warning.  I have read that methanol is very corrosive to metal 
parts, while ethanol is not.  I don't know if ethanol will work in that 
application. 

Ethanol costs more than gasoline, methanol costs much less;  many 
SoCalif gas suppliers/stations have been accused of diluting their gas 
with methanol, causing serious damage to untold numbers of cars.  
Ethanol will counter the corrosive effects of methanol, if added in the 
right proportion.

But now, I have read that the new oxygenated fuel has methanol..
There is an apparent increase in the number of car fires with it; 
probably due to corroded fuel pressure regulators.  It happened to my 
'81 Vanagon last year.  Fuel pressure went over 100psi, and leaks 
sprung up in lots of places.

Post-mortem on the regulator showed it to be badly rusted inside.
The input was also clogged with an unknown substance, like maybe rust 
crud from other parts.
