Good idea Mr B. That etha*** really puts me in a bad mood.
I just changed most of my fuel system on my old Ford pickup. Accelerator pump, fuel pump and the tank sending unit. I run a product called startron in everything now because eth-free gas is pretty pricey. (Forgive me as you probably know this)-The way it was explained to me is it is suppose to keep the corn-water-poo from bonding together on a molecular level. So far it seems to work but only time will tell.
