The trick is indeed to remove all traces of gasoline an gas vapour. Lucky
for us gas evaporates easily. I use a shop vac or other type of  vacuum
cleaner and blow a steady stream of air through the tank thus promoting
evaporation. About 1/2 hour of this will suffice.
My first welding a gas tank experience ended up with a large bang and a
medium sized flood in my workshop after I followed some "experts" advice to
fill a motorbike tank with water leaving just a small bubble of air near the
pinhole to be fixed. the minuscule amount of "air"(and fuel vapour) was
enough to render the tank shaped like a pumpkin and me soaked and stunned.
I was lucky.and learned my lesson

  When applying serious heat to a fuel tank I have always rinsed them twice
with water and then dried them with warm air from a hair drier. Then I
pressed paper tissues into the corners to absorbe whatever moisture may have
remained in there and finally, when welding or soldering, I inserted an air
hose from the compressor and blew air through the tank.

  This seems to work quite well. I haven't drawn the trip to the moon yet...

  The tank necks are easily salvaged as they are only soldered in, but the
usual reminder that tanks are highly explosive, so they have to be removed
with part of the tank before the heat is applied.  The same applies to all
the other bits.

    I don't know how much the previous ones were as I think I joined the
club just as the last ones were being sold. Yr 2000  I think. Guess I need
to have a go at doing one and see how it goes.
