Guys currently the back of the tank sits about 3" short of the tailpipe exit, so a small portion of it is below the point where the turbine reduces down in diameter to the cone area, and the turbine is unlikely to be moved now as the tailpipe dictates its position.
I am not totally happy with it, but if protecting it will work then this might have to do[

I was looking into custom tanks but they seem very expensive........................ how easy are they to make? Any offers out there?

just do some testflights with a empty tank and look for discolouration.
if i remember correct kerosene boils at about 75 celcius at msl? then it gets spectacular.
but the position is tricky.
cant you use a drop tank?
or use a duct around the engine?
