[QUOTE="oexing, post: 168042, member: 1493"] All these old tales about ethanol blaming for any leaks in fuel systems. It is the thinners in modern fuel, like acetone, butan, toluol and all that dissolves seals or softens epoxy tanks - a problem I have watched for many years already . If ethanol (alcohol) were the problem, your whiskey distillery would know since centuries about any problems with rubber hoses or seals. The only brew of fuel still like from olde times is avgas - when you accept the price. For sealing a leaking tank or rust prevention I have found G 4 polyurethane single pack clear paint to be safe with modern fuel. My tests in several tanks run more than 30 years , never any troubles from that paint - if that will do for you for long time testing . Single pack is quite economic as you can store it for months once opened , it just turns into more like honey after longer storage. There were some more "tank sealers" on epoxy base but I would not take the risk today, people had big troubles with them after flaking off and you´d need to get the rest out of the tank somehow - a gigantic mess then.
