Mogas handling leaves a lot to be desired regarding exact content of the product as pumped versus that which is advertised. Avgas is certified to be alcohol-free, but it certainly is not free. How much longer Avgas will be available is also in question. I still recommend that composite fuel tanks be constructed with vinyl ester resin for best chemical endurance. The styrene fumes from the curing vinyl ester resin can be handled with plenty of ventilation plus a charcoal respirator. Sanding vinyl ester is a frustrating chore, but then there is not that much to do for a fuel tank. Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD USA sidney.w...@titan.com
Sid's statement may result in someone thinking that they could use the gas without alchohol in it and not have trouble with the epoxy used to make the fuel tank. I have worked with the fire marshal's office here in town and from what I heard, the alchohol content of commercially available gas is not reliable due to storage at the fueling facility. In short, one may think they are getting alchohol free mogas but that may not be the case. Ameet Savant ameetsavant at yahoo dot com > It is not the gasoline that does the > damage to the epoxy.
