One thing I recommend to those new to gas is NOT to use a stopper at all for your tank. They are a serious failure point, and fail they do, often. Gas compatibale or not. You want a tank with a screw on cap. Bennet built makes them. The Fiji water bottle is good too. There is a company that sells a ready to run tank that is only 8 oz. that would be perfect for this engine. I ran it for 2 years on my DLE 20, but replaced it for a larger one this year. I will post a link when I find it.

My IBEC is optically isolated and also incorporates a kill switch as well. Valley view sells these and they are manufactured by RCXcel. I just have not tried it out yet.
