i'm thinking of making my own water methanol injection instead of going with Snow's kit..

i just have no clue if the windshield washer pump puts out enough to mist.

anyone ever messed with this?

I would use a Surflo pump. There used in RV and in ag. sprayers. There higher pressure then windshield washer pumps and not real spendy either. One like this is what I used.
