Bill Hirsch Tank Sealer - 2002 - Ethanol

[Hunter]

Didn't get any traction on this question when I responded to a more general post on tank sealers, so I though I would try again.

Around 2002 I used the Bill Hirsch sealer in my gas tank after having it chemically dipped to clean it out. After completing the restoration, around 2012, I decided to use ethanol free gasoline as I had read somewhere that the use of gas with ethanol could attack a sealer and cause it to come loose and clog things up. I don't believe a particular sealer was mentioned and I have no idea where I read this info.

The area that I live in has no ethanol free gas stations. The closest one being in Berlin Md, a considerable distance away. (I have used the internet site that lists the ethanol free stations in an attempt to find one). So in order to keep it ethanol free I have being using high octane racing fuel which is stated to be ethanol free. I have tested it to be sure that it is indeed ethanol free. This gas is very expesnive ($6.50 a gallon) and not always readily available.

So my question is --- for people that have the Bill Hirsch sealer from say the year 2000 forward, have you had any issues with gasoline with ethanol attacking the sealer? I hope not, as I want to start driving this car more and would really like to run gasoline with ethanol without fear of it attacking the sealer.

Thank you - Hunter
