    its easy to see that there isn't too much regulation on the quality and consistency in the blend of the fuel we buy...it should say at every pump that it "CAN contain UP TO 10% ethanol"...so pretty much between 0 and 10% ethanol.

    if its e85 it has 85% ethanol, that is the stuff you can find all over the midwest. and from what i here, can be even worse on consistency in the blend. however...i still am hoping to run it in my boat when its more available in cali.

I learnd about this crap in a C.A.R.B. class I had to take to make all the "little" engine complient.I didnt pay much attention to this part of the lecture.....lol. Whole different ballgame the out here.

    Remember the Nordic? The tanks were deterating from the inside out.

(one of the most controled states) that sets the standards for all stations and I highly doubt they would let you put a tank in the ground that eats its self away after yeas of service.. just my .02

    Don't worry about the cylinders, just get the heads (valves and guides) cleaned up and drive it.

    Thanks for the recommendation.

    Anyone got anybody else?

    Do i have to worry about being certified or replacing above deck tanks?

    What is best? Stainless? Alum? plastic?

    any problems with above deck regulations?

    I am in the middle of fabbing up a replacement alum bow tank for this very reason. My old fiberglass bow tank is riddled with soft spots and small pinholes where I assume the resin has been attacked by something, assuming ethanol since ohio has up to 10% blend for at least 5 years.
    My aluminum intake ports on old engine showed a black glossy hard substance coating each of the intake runners. I assume this is recrystallized resin where it was in solution with the gas/ethanol thru the carb, then hit the hot runners and stuck to them. Anyone know a good way to clean this crap off??
    My next concern is the rubber fuel lines. I was thinking it would be safer to replace it with hardline anyway, so I might do that. But is normal black fuel/emission hose rated for ethanol? I cant run hardline the whole way, will have to have some rubber transition pieces here and there.

I'm not trying to jump on the bandwagon blindly, but the tanks were cracking and leaking also. It could be sediment/varnish, but I have seen that and this looked nothing like what I have seen in the past.

    More fuel for the fire so to speak. This article speaks of the black reside the OP talked about.

    On an unrelated note, I had to take my 2007 Lexus in for a recall on the fuel lines not long ago. It seems the ethanol is eating away the lines. I have two friends that are long time Lexus mechanics. One at each of the Dallas dealers. They have both seem first hand lines with pin holes in them for the erosion caused by ethanol. According to my one mechanic fried fuel pump failures were also on the rise with the addition of ethanol as an additive.

    As for the post about the "competition" between gas stations, It has to do with emission and non-emission counties, It is not up to the station if they have ethanol as an additive or not.

    I went through this on my Spectra 24XS. Ethanol ate the tanks away and filled the motor with badness. The only solution was a rebuild of the motor and replacment of the tanks. IMCO built me two new 33.3 gallon tanks for just under $1000 bucks out the door.
