No, not air tight, I fitted a non return breather, that allows air to replace used water volume but won't allow a fluid leak even if I roll it.hmmm... I've still got my 50L water tank hooked up for my drinking water and general usage outlet hose as well as the water injection. Plus it's not air tight as I have a breather running up the cargo barrier so now that I think more about it I probably will need another dedicated tank for the meth. Meth tanks need to be air tight right otherwise the meth goes bad? Thinking I might just run a temporary tank for testing the water/meth mix before I commit, who knows maybe I'll just be happy with the straight water only. I'm pretty happy with the 150 degrees it's dropped so far with the manifold injection which will allow me to run more diesel. Plus I haven't tried the pre-turbo yet so who knows how much better it'll get.
Found a fuel supplier in Eagle Farm who will deliver 20L meth drums to my door for $46 each. How much are others paying for your meth?
$46 is pretty good I'm paying a bit more due to extra transport costs.
