hello all

do you expect problems with condensated water in the fueltank

how do you handle that problem, or do you simply ignore it ?
are there any technical tipps, additives for the gasoline or
other things to do ?

Oh boy.

Well, let's put it this way. Depending on the size and type (glass,
metal or poly), it could be a problem, but most likely not.

If you have a 50 plus gallon tank, then the best thing to do is
as Chuck says - fill it to reduce surface area and add a good
stabilizer like E-Zorb. Depending on where you live, ethanol
can be a concern depending on the local mix of ethanol is. In
some areas of the country, E-10 is like E-25 - alcohol/gas and
water don't mix well and you could suffer from some ethanol/water
seperation problems.

Does you engine have a fuel/water seperator? If not, I'd put one
on if you can justify it - like a retro fit. Racor sells a really
good retro-fit device for their poly/glass bottom filters - pretty
simple to maintain.

If it's a 6 gallon tank, then I wouldn't worry about it - just use
a little E-Zorb (just in case) and leave it alone - your aren't
going to have much of a problem.
