Since you've actually done it and had problems, then I thank you for setting the record straight.

It fooled me, because this did not occur immediately.
I pulled the tank from a plane I had run 1/2 a season only to discover the disintegration of the fuel plug.
As RCKen said...going the other way... I've had plastic plug retaining plates which replace the metal ones sometimes used, DISSOLVE(!!!) when used in glow fuel in the matter of a few days or weeks!
e.g. I pulled the plug & assembly from an GASSER ARF and put it in a glow tank without thinking... BIG MISTAKE...
