Glow fuel can last for many years if it is completely sealed and stored at room temperature in a dark place. However, the slightest compromise of the seal can allow moisture to be absorbed into the methanol in the fuel, or allow the nitromethane and methanol to evaporate. I have used tightly sealed (previously unopened) glow fuel that was over 10 years old and it still worked fine. I have also seen fuel less than a year old that was useless due to absorbed moisture and contents evaporation. If you stored the fuel in a jug with a cap having a fuel dispensing hose stuck in the top, then the answer is almost certainly spoiled fuel, especially if it was stored in non-climate controlled space. Store it in a barn and the daily temperature variations will pressurize and depressurized the container, causing moisture laden air to be sucked into and forced out of the jug, causing moisture contamination. Bad fuel can cause poor idle, loss of top end power and flameouts when the glow plug is disconnected. If it is less than 10 years old and never opened, then it is probably worth giving it a try, especially considering that fuel currently goes for $25 to $35 per gallon depending on location, shipping costs and nitro content. The only way to know is to try it.
