No problems at all. Rings and seals designed for gas will stand up to nitro with no problems. But not the other way around. Seals and rings designed for nitro will not stand up to gas. That is why we have to change the stoppers in fuel tanks if you intend to use gas in them.
Carefull here...
I've had RUBBER stoppers designed for gas disintegrate over time when I've used them for glow fuel.
The rubber becomes "grainy" and sloughs off in little rubber flags or bits, that can easily make it into the carb.
While a filter helps with this, I've taken to replacing these stoppers.
Also Glow fuel's hydroscopic nature tends to corrode metals that can rust, while gasoline in the same containers will not rust nearly as quickly.
A plastic glow fuel container will hold up better over time.
