Gas Gauge Float comes in two versions (Epoxy-Coated Cork and Modern Neoprene Cork).
Epoxy-Coated Cork Float: When replacing the float on the wire, follow it with a washer and a drop of solder to secure the float in place.
Modern Neoprene Float: This float is alcohol and gas resistent, and will not sink. It is not affected by modern ethanol based fuels. Highly recommended. USA made.
