Also look at where the pipe enters the house, where the outer plastic coating stops, as you just had a fill of fuel, possibly the delivery driver disturbed the tank fitting, it can leak and run the whole length of the pipe between the pipe and coating and end up inside the house.
As Shane suggests, check everywhere at your burner and pipework for any wetness, the smell from you initial bleed should be long gone by now, the fact you can now smell it in you hall suggests a small leak somewhere
If in doubt, get someone out to check it for you, as oil can damage your house, and be exspensive to repair
