I believe the answer would have to be a qualified yes. The problem is not the alcohol attacking the tygon but rather the tygon by nature is stiffer than silicone tubing and not nearly as supple with the result being an internal clunk tube that does not 'clunk' around much easily leading to running problems in flight.

The Hayes tanks before their recent demise were marketed as usable for both glow and gas and the way they got around the stiff tygon clunk line was to use a different type tubing yet and this was a black neoprene tubing. very flexible but perhaps not as durable as tygon.
