All our fuels come in UN approved steel drums. All drums have a 2 inch BSP bung, they are designed for safe transport and storage but do not pour very well. To avoid spillage, it is best to use a pump to decant your fuel. We have a couple of different pump options which are available in our web shop. It is best to keep unused fuel in the drum supplied with the drum bung sealed tight. Race fuels will only really deteriorate if vapours can escape or moisture can get into the drum. For this reason, we would not recommend leaving race fuel in your fuel tank for an extended period of time - this is particularly important if the fuel in question contains ethanol. Any drained fuel is best kept in a separate container to the fresh, unused race fuel.
Try and store your fuel where it is not exposed to wide temperatures swings, i.e. outside.
