			On my 19' wellcraft 1986 the tank is poly I was also concerned that the e-10 gas maybe a problem. I called wellcraft and they said that there is no problem with the tank and todays gas, but that the gas fill and vent line must be replaced as they would be a problem. As I have the floor ripped out now I would have changed the tank. Now I'll just change the gas lines along with the stringers and deck. All I need is some nice warm weather to start this work. I just picked up a 1989 Mako 220 with a evinrude 225 E-tec (2007) yes I'm also a member of the classicmako site.
