I don't know what a "pile" of fuel is. I assume you mean a container full of it.
Gasoline needs oxygen to burn, and it needs the correct mixture. Too little oxygen and burning is impossible. Too much oxygen causes the same problem. To achieve ignition with Gasoline, you need between 1.4 and 7.6% petrol vapour (by volume) in the air. Ouside this range burning will not start.
If these conditions are met, as the flash point of gasoline (the minimum temperature at which it will burn) is $-40C$, your red-hot poker will do the job. In fact, gasoline and air will self-ignite at around $250C$. For more details, start with the Wikipedia article on the Flammability limit.
